Questions and Answers

1.

Please select the force on the picture that is caused by gravity.
2.

A force that tries to slow things down, when two things rub together is called.
- A.
  
  Gravity
- B.
  
  Upthrust
- C.
  
  Friction
- D.
  
  Motion
Correct Answer
C. Friction

Explanation
Friction is the correct answer because it is the force that opposes the motion of two surfaces in contact with each other, causing them to slow down.

What determines if the forces acting on an object are balanced?
- A.
  
  Opposite direction
- B.
  
  Equal magnitude
- C.
  
  Same direction
- D.
  
  Different magnitude
Correct Answer(s)
A. Opposite direction
B. Equal magnitude

Explanation
Forces acting on an object are balanced when they have opposite directions and equal magnitudes. This means that the forces are equal in strength but act in opposite directions, resulting in a net force of zero. When the forces are balanced, the object remains at rest or continues to move at a constant velocity.

Which two forced act on a floating object?
- A.
  
  Gravity
- B.
  
  Down thrust
- C.
  
  Up thrust
- D.
  
  All of the above
Correct Answer(s)
A. Gravity
C. Up thrust

Explanation
When a object is floating, it is being supported by the upward force called up thrust, which is exerted by the fluid (usually water) in which it is floating. This up thrust counteracts the downward force of gravity, allowing the object to remain buoyant and float. Therefore, both gravity and up thrust are the two forces that act on a floating object.

Fill in the blanks Friction is a force that ________ or ________ motion when objects rub together. The ________ the surfaces are the faster the objects will stop.

Correct Answer(s)
slows
stops
rougher

Explanation
Friction is a force that slows or stops motion when objects rub together. The rougher the surfaces are, the faster the objects will stop.

Fill in the blanks Gravity ________ to the center of the Earth. A piece of Equipment that is used to measure forces is called ________. The unit of force is ________. Air ________ on a falling object is called upthrust.

Correct Answer(s)
pulls
Newton metre
Newton
resistance

Explanation
Gravity is the force that pulls objects towards the center of the Earth. A Newton meter is a piece of equipment used to measure forces. The unit of force is Newton. The air resistance on a falling object is called upthrust.

Three simple machines are....?
- A.
  
  Wind turbine
- B.
  
  Gears
- C.
  
  Engines
- D.
  
  Wheels
- E.
  
  Leavers
- F.
  
  Cranes
- G.
  
  Pulleys
- H.
  
  Screwdriver
Correct Answer(s)
B. Gears
E. Leavers
G. Pulleys

Explanation
The correct answer is gears, levers, and pulleys. These are all examples of simple machines that can be used to multiply or change the direction of force. Gears are used to transmit power and motion between rotating shafts. Levers are used to lift or move heavy objects by applying force at one end and using a pivot point. Pulleys are used to lift heavy objects by redirecting force through a system of ropes or cables.

The image below shows a tug of war before and after the teams have started pulling, which direction do you think the rope will move?
- A.
  
  Up
- B.
  
  Left
- C.
  
  Down
- D.
  
  Right
Correct Answer
B. Left

Explanation
Based on the image, it can be inferred that the team on the left has more people and is exerting a greater force compared to the team on the right. Therefore, the rope is likely to move towards the left direction, as the team with more force will overpower the other team and pull the rope in their direction.

Fill in the blanks the describe how the magnets will react. Positive and positive ends will ________. positive and negative ends will ________. negative and negative ends will ________.

Correct Answer
repel
attract
repel

Explanation
Positive and positive ends of magnets will repel each other, as like poles repel. Positive and negative ends of magnets will attract each other, as opposite poles attract. Negative and negative ends of magnets will repel each other, as like poles repel.
