Question

What change(s) will you definitely observe when a force is applied to an object?

• A. Move an object forward
• B. Stop a moving object
• C. None of the these
• D. Change the shape of an object

Answer 1

Answer: (A), (B), (D)

The correct options are
A

Move an object forward

B

Stop a moving object

D

Change the shape of an object

When a force is applied to an object, we may observe the following:

1. The object may start to move or its speed might increase.
2. A moving object may stop or its speed might decrease.
3. The direction of the moving object may be changed.
4. The shape of the object may be changed.

It is not necessary that when we apply a force on an object the following changes will be observed. For example, when we apply a force to a wall it doesn't move, neither does its shape change.
