Question

What does Newton's second law of motion state?
a. Force equals mass times acceleration
b. An object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force
c. Momentum equals mass times velocity
d. For every force there is an equal an opposite force.

Answer 1

Newton's second law of motion states: **a. Force equals mass times acceleration**. This law can be expressed with the formula \( F = ma \), where \( F \) represents force, \( m \) represents mass, and \( a \) represents acceleration.
