Question

What causes the change in motion and change of state of motion?

• A. Pressure
• B. Force
• C. Atmospheric pressure
• D. Fulcrum

Answer 1

The correct option is B

Force

Explanation for the correct option:

Option B- Force

1. Force is the push or pull that acts on an object.
2. If the body is in rest then it continues to be in rest and if the body is in motion then it will continue to be in motion unless or until the external force is applied to it.
   Explanation for the incorrect option:
   Option A-Pressure
3. Pressure is the force per unit area.
4. Pressure can change the volume of fluids.
   Option C- Atmospheric Pressure
5. Atmospheric pressure is the force experienced at any point on the earth's atmosphere by the air above it.
6. Atmospheric pressure can't affect change in state or change in motion of the object,
   Option D-Fulcrum
7. The fulcrum is the point on which the lever turns or balances.
8. Fulcrum can't affect change in state or change in motion of the object,
   Hence, option (B) is the correct answer.
