Newton's third law states that:

F = ma
Object stays at rest until pushed
Every action has an equal opposite reaction
Momentum is conserved

Show answer and solution

Correct answer: C. Every action has an equal opposite reaction

Third law: action and reaction are equal in magnitude, opposite in direction, and act on different bodies.

Momentum p of a body is given by:

p = ma
p = v/m
p = F/t
p = mv

Show answer and solution

Correct answer: D. p = mv

Linear momentum p = m × v. Unit: kg·m/s. Conserved in absence of external force (law of conservation of momentum).
