- A force is a thrust
- A force is something that needs to be reduced
Correct Answer

A. A force is a push or a pull

Explanation

The correct answer is "a force is a push or a pull" because a force is a physical interaction that can cause an object to move, change its speed, or change its direction. Pushing and pulling are common examples of forces that can be exerted on an object to make it move or change its position.

A force is a push or a pull and they cannot br seen.
- True
- False
Correct Answer

A. True

Explanation

This statement is true because a force is a concept in physics that describes the interaction between two objects, where one object exerts a push or pull on the other. Forces are not visible to the naked eye but their effects can be observed through the motion or deformation of objects. Therefore, forces cannot be seen directly but their presence and effects can be observed and measured.

List the parts of bicycle
- A.friction is essential
- B.friction must be reduced
Correct Answer

A. A.friction is essential

Explanation

The given correct answer states that friction is essential in a bicycle. This means that friction plays a crucial role in the functioning of a bicycle. Friction is necessary in various parts of a bicycle such as the brakes, tires, and chain. Without friction, the brakes would not be able to stop the bicycle, the tires would not grip the road, and the chain would not be able to transfer power to the wheels. Therefore, friction is essential for the proper operation and control of a bicycle.

_______ is the force that opposes motion between two surfaces in contact.

Correct Answer
Friction, friction

Explanation
Friction is a force that opposes motion between two surfaces that are in contact. It arises from the microscopic irregularities on the surfaces, which interlock and resist sliding. Friction is responsible for many everyday phenomena, such as the ability to walk, the slowing down of a moving object, and the generation of heat.
