What energy is present in moving object?
- A.
Chemical Energy
- B.
Potential Energy
- C.
Kinetic Energy
- D.
Nuclear Energy
Correct Answer
C. Kinetic EnergyExplanation
Kinetic energy is the energy possessed by an object due to its motion. When an object moves, it has the ability to do work and transfer energy to other objects or systems. This energy is known as kinetic energy. It depends on the mass and velocity of the object. The faster an object moves or the heavier it is, the more kinetic energy it possesses. Therefore, kinetic energy is the correct answer for the energy present in a moving object.Rate this question:

3. Which of the following statement is true?
- A.
Friction makes an object slide
- B.
Gravity pushes an object upward
- C.
Force is needed to stop an object
- D.
An object in motion will remain in motion
Correct Answer
D. An object in motion will remain in motionExplanation
This statement is based on Newton's first law of motion, also known as the law of inertia. According to this law, an object in motion will continue to move in a straight line at a constant speed unless acted upon by an external force. This means that if no force is applied to an object in motion, it will continue to move indefinitely.Rate this question:

- A.
The baseball will land first.
- B.
The paper will float slowly through the air.
- C.
The baseball will float slowly though the air.
- D.
The baseball and the paper will land at the same time
Correct Answer
D. The baseball and the paper will land at the same timeExplanation
If there is no air resistance, both the baseball and the sheet of paper will experience the same acceleration due to gravity. This means that they will fall at the same rate and will therefore land at the same time. The mass of the objects does not affect their rate of fall in the absence of air resistance.Rate this question:

A boy sits on a grassy slope. What force stops him from sliding down?
- A.
Friction
- B.
Magnetic force
- C.
Gravity
- D.
Motion
Correct Answer
A. FrictionExplanation
Friction is the force that stops the boy from sliding down the grassy slope. When the boy sits on the slope, the friction between his body and the grass provides a counteracting force against the downward pull of gravity. This frictional force acts in the opposite direction to the sliding motion, preventing the boy from moving down the slope. Without friction, the boy would slide down due to the force of gravity.Rate this question:

The boat sailing on the sea slows down. What kind of friction is acting on it?
- A.
Rolling Friction
- B.
Static Friction
- C.
Sliding Friction
- D.
Fluid Friction
Correct Answer
D. Fluid FrictionExplanation
When a boat is sailing on the sea, it experiences fluid friction. Fluid friction, also known as drag, is the resistance that occurs when an object moves through a fluid, such as air or water. In this case, as the boat moves through the water, the water molecules exert a force on the boat, causing it to slow down. This force of fluid friction opposes the motion of the boat and is responsible for its deceleration.Rate this question:

Third Class Lever
Correct Answer
C. Third Class LeverExplanation
A lever is a simple machine that consists of a rigid bar that rotates around a fixed point called a fulcrum. In a third class lever, the fulcrum is located at one end of the lever, the effort is applied at the other end, and the load is located between the fulcrum and the effort. This means that the load is closer to the fulcrum than the effort, resulting in a mechanical advantage less than 1. In the case of tweezers, the fulcrum is the pivot point where the two arms meet, the effort is applied by squeezing the handles, and the load is the object being grasped. Therefore, tweezers can be classified as a third class lever.Rate this question:

Falling objects on Earth pass through air.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Objects falling on Earth do pass through air. When an object falls, it experiences air resistance, which is the force exerted by the air on the object as it moves through it. This resistance opposes the motion of the object and causes it to slow down. The amount of air resistance depends on factors such as the size, shape, and speed of the object. Therefore, it is true that falling objects on Earth pass through air.Rate this question:

Friction converts some energy into heat and causes wear and tear on materials.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Friction is a force that opposes the motion of objects in contact with each other. When objects rub against each other, the friction between them converts some of the energy into heat. This heat generation is why we feel objects getting warm when we rub them together. Additionally, friction can also cause wear and tear on materials as the surfaces rub against each other, leading to the gradual degradation of the materials over time. Therefore, the statement that friction converts energy into heat and causes wear and tear on materials is true.Rate this question:
