Front

What is the result of unbalanced forces?

Back

Motion

Front

What does Newton's second law state?

Back

Force is dependent upon mass and acceleration.

Front

What is the formula to calculate acceleration?

Back

Acceleration = Force / Mass.

Front

What is air resistance?

Back

A force that slows motion.

Front

How do you calculate force?

Back

Force = Mass x Acceleration.

Front

What is the unit of force in the SI system?

Back

Newton (N).

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

They are inversely proportional when force is constant.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

It will start to move.

Front

What is equilibrium in terms of forces?

Back

When all forces acting on an object are balanced.
