3A Test: Laws of Motion MAKE-UP

Front

What is Newton's First Law of Motion?

Back

An object in motion stays in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is dependent on the net force acting upon it and its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is gravity?

Back

A force that pulls objects towards the Earth.

Front

What is a balanced force?

Back

When two forces act in opposite directions and are equal in size, resulting in no change in motion.

Front

What happens when forces are unbalanced?

Back

An object will accelerate in the direction of the net force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the formula for calculating force?

Back

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

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.
