4.9.1 Forces and Newton's laws (A-level only)

What quantity determines how an object's motion changes?

A

The resultant force.

B

Newton's second law is ∑F=ma\sum \mathbf{F}=m\mathbf{a}∑F=ma, and acceleration acts in the same direction as the resultant force.

C

Perpendicular to the contact surface.

D

Every external force acting on one isolated object.
