Question

Which statement is true according to Newton's second law of motion? A. An object accelerates in the direction opposite to the direction of the force applied. B. An object accelerates in the direction perpendicular to the direction of the force applied. C. An object accelerates in the same direction as that of the force applied. D. An object undergoes no acceleration on the application of force. E. An object’s acceleration is independent to the force applied.

Answer 1

According to Newton's second law of motion, C. an object accelerates in the same direction as that of the force applied.

You don't see this when you see the 2nd law's formula written as Force=mass·Acceleration ... there doesn't seem to be any information about directions there.

The thing is that this is supposed to be a VECTOR equation, like Force=m·Acceleration . Written like that, it says that Force and Acceleration are vectors, and both sides of the vector equation have the same direction, so the vectors Force and Acceleration both have the same direction.

Answer 2

C. An object accelerates in the same direction as that of the force applied.

Step-by-step explanation:

An object accelerates in the same direction as that of the force applied.
