Front

Calculate the force if mass is 10 kg and acceleration is 5 m/s².

Back

50 newtons (F = 10kg x 5m/s²).

Front

What does Newton's 3rd law state?

Back

For every action, there is an equal and opposite reaction.

How do you find acceleration using the equation 20N = 10kg x a?

Back

Acceleration is 2 meters per second (a = 20N / 10kg).

Front

Define momentum.

Back

Momentum is the product of mass and velocity (p = m x v).

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = m x a).

State Newton's 1st law of motion.

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
