Motion

Q.

1. False
2. True

Q. When is a body said to be at rest?

1. A body is said to be at rest when its acceleration doesn't change with time.
2. A body is said to be at rest when its acceleration changes with time
3. A body is said to be at rest when its position change with time.
4. A body is said to be at rest when its position doesn't change with time.
