Question

A force F is applied to a freely moving object. At one instant of time, the object has velocity v and acceleration a. Which quantities must be in the same direction?
A. a and v only
B. a and F only
C. vand F only
D. v, F and a​

Answer 1

The correct answer is a and F only.

F and an as F =ma, F and a have the same direction since m is a scalar.

For instance, when an object is thrown up, its velocity is upward, yet its acceleration is downward and its force is upward.

What is Force?

When applied, force is defined as an external cause that, depending on the body's state—if it is in motion, it will come to rest; if it is at rest, it will go into motion. The body's direction, shape, size, etc. may also change as a result.

What is Acceleration?

When applied, force is defined as an external cause that, depending on the body's state—if it is in motion, it will come to rest; if it is at rest, it will go into motion. The body's direction, shape, size, etc. may also change as a result. Example: Using force to push or pull a door.
