Forces and Newton's Laws of Motion

Front

What is a force?

Back

A force is a push or pull on an object.

Front

What is inertia?

Back

Inertia is an object's resistance to change in its state of motion.

Front

What does Newton's 1st law of motion state?

Back

An object at rest remains at rest, and an object in motion remains in motion unless acted upon by a net external force.

Front

What is Newton's 2nd law of motion?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is Newton's 3rd law of motion?

Back

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

Front

How does mass affect force in a collision?

Back

The player with greater mass will exert more force during a collision.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration in Newton's 2nd law?

Back

As mass increases, for a constant force, acceleration decreases.

Front

What is the formula for calculating force?

Back

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

Front

What is an example of inertia in everyday life?

Back

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