• 1.

### For every action, there is an equal and opposite reaction.

• A.

True

• B.

False

A. True
Explanation
This statement is one of Newton's third laws of motion. It means that for every force applied on an object, there is an equal and opposite force exerted by the object in the opposite direction. This law is applicable to all types of forces, whether it is a push, pull, or any other interaction between objects. It helps explain the concept of balanced forces and the conservation of momentum in physics.

### According to Newton's third law, for every action force there is an equal (in size) and opposite (in direction) reaction force. Forces always come in pairs - known as "action-reaction force pairs."

• A.

True

• B.

False

A. True
Explanation
Newton's third law states that for every action force, there is an equal and opposite reaction force. This means that whenever an object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. These forces always come in pairs, known as action-reaction force pairs. Therefore, the statement "True" is correct because it accurately reflects Newton's third law.

### Describe the other force in the action-reaction force pair.

• A.

The glove pushes the baseball rightward.

• B.

The glove pushes the baseball upward.

• C.

The glove pushes the baseball downward.

• D.

None of the above.

A. The glove pushes the baseball rightward.
Explanation
The other force in the action-reaction force pair is the baseball pushing the glove leftward. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, when the glove exerts a force on the baseball to push it rightward, the baseball exerts an equal and opposite force on the glove to push it leftward.

### Describe the other force in the action-reaction force pair.

• A.

Pin pushes bowling ball rightward.

• B.

Pin pushes bowling ball upward.

• C.

Pin pushes bowling ball downward.

• D.

None of the above.

A. Pin pushes bowling ball rightward.
Explanation
The other force in the action-reaction force pair is the bowling ball pushing the pin leftward. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the action is the pin pushing the bowling ball rightward, and the reaction is the bowling ball pushing the pin leftward. Therefore, the correct answer is "Pin pushes bowling ball rightward."

### Describe the other force in the action-reaction force pair.

• A.

Balloon wall pushes enclosed air particles inwards.

• B.

Balloon wall pushes enclosed air particles outwards.

• C.

Balloon wall pushes enclosed air particles upwards.

• D.

None of the above.

A. Balloon wall pushes enclosed air particles inwards.
Explanation
The correct answer is "Balloon wall pushes enclosed air particles inwards." When the balloon wall is pushed inwards, it exerts a force on the enclosed air particles, causing them to move in the opposite direction, which is inwards as well. This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

### According to Newton's third law,The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

• A.

True

• B.

False

B. False
Explanation
This is actually Newton's 2nd Law of Motion.

### The Law of Conservation of Momentum states that

• A.

All the momentum in a system before a reaction is greater than the momentum after a reaction.

• B.

All the momentum in a system before a reaction is less than the momentum after a reaction.

• C.

All the momentum in a system before the reaction is the same as all the momentum after the reaction.

• D.

All the momentum in a system before a reaction is lost during the reaction so none is left following the reaction.

C. All the momentum in a system before the reaction is the same as all the momentum after the reaction.
Explanation
The Law of Conservation of Momentum states that the total momentum of a system remains constant before and after a reaction, as long as no external forces are acting on the system. This means that the sum of the momenta of all the objects involved in the reaction remains unchanged. Therefore, the correct answer is that all the momentum in a system before a reaction is the same as all the momentum after a reaction.

### Johnny hits sally with a kickball while playing dodgeball in gym class.  The momentum that he hits her with is the same amount of momentum that the ball has when it bounces off sally... In other words, no momentum was lost in the reaction.

• A.

True

• B.

False

A. True
Explanation
According to the principle of conservation of momentum, the total momentum of a system remains constant if no external forces act on it. In this scenario, when Johnny hits Sally with the kickball, the momentum he imparts to her is equal to the momentum that the ball has when it bounces off Sally. This means that the total momentum of the system (Johnny + kickball + Sally) remains the same before and after the interaction. Therefore, no momentum is lost in the reaction, making the statement true.

### Knowing Newton's Third Law of Motion and the Law of Conservation of Momentum, would you rather ride in a modern car that is light and small but has lots of safety standards built in or a big, heavy older car that lacks some of the safety standards (remember the collision video)?

• A.

Newer car with safety standards because they are built to withstand the momentum of the collison.

• B.

Older car without safety standards because the huge mass of the older cars means I will be safer in a collision.

• C.

Newer car with safety standards because the gas mileage is better so less chance to get into an accident.

• D.

Older car without safety standards because the gas mileage is so high I wouldn't be able to afford the gas to drive in it much, so less chance to get into an accident.

A. Newer car with safety standards because they are built to withstand the momentum of the collison.
Explanation
The correct answer is that one would rather ride in a modern car that is light and small but has lots of safety standards built in. This is because newer cars with safety standards are designed to withstand the momentum of a collision, which means they are better equipped to protect the occupants in the event of an accident. The reference to Newton's Third Law of Motion and the Law of Conservation of Momentum suggests that the safety standards in the newer car would help to mitigate the effects of the collision and potentially reduce the risk of injury.

### Momentum is not always conserved - some could be lost in the system.

• A.

True

• B.

False

B. False
Explanation
Momentum is always conserved in a closed system according to the law of conservation of momentum. This means that the total momentum before an event or interaction is equal to the total momentum after the event or interaction, as long as no external forces are acting on the system. Therefore, the statement that momentum could be lost in the system is incorrect.
