Front

What best describes Newton’s 3rd Law of Motion?

Back

The wall pushes back on you as hard as you push on the wall.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a)

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the work done formula?

Back

Work = force × distance (W = F × d)

Front

How do you calculate weight?

Back

Weight = mass × acceleration due to gravity (W = m × g)

Front

What is the unit of force in the SI system?

Back

Newton (N)

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
