Front

What is Newton's First Law?

Back

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

Front

What is the net force?

Back

The overall force acting on an object, taking into account all individual forces.

Front

What does Newton's Second Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it resists changes in its state of motion.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating net force?

Back

Net force = mass x acceleration (F=ma).

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.

Front

What is an example of Newton's Second Law in action?

Back

A heavier object requires more force to accelerate than a lighter object.
