Newton's Laws

Front

What is an unbalanced force?

Back

An unbalanced force means that an object is changing its motion.

Front

Which law explains why a sports car speeds up faster than a dump truck?

Back

This is explained by Newton's Second Law.

Front

What does Newton's Third Law state?

Back

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

Front

What must be true if an object is accelerating?

Back

The forces acting on it must be unbalanced.

Front

What is a force?

Back

A force is a push or pull on an object.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

How does mass affect acceleration according to Newton's Second Law?

Back

The greater the mass of an object, the less acceleration it will have for a given force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What happens to an object when balanced forces act on it?

Back

The object remains at rest or continues to move at a constant speed.
