Newton's Laws of Motion

Front

An object's motion won't change unless acted on by a _________

Back

force

Front

The force that pulls objects down towards the center of the Earth is called _________.

Back

Gravity

Front

_______ force is needed to move objects of larger mass.

Back

More

Front

______________ forces do not affect the movement of an object.

Back

Balanced

Front

For every action there is ______ and opposite reaction.

Back

an equal

Front

What is the first law of motion?

Back

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

Front

What does the second law of motion state?

Back

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

Front

What is the formula for Newton's second law?

Back

F = ma (Force = mass x acceleration)

Front

What is inertia?

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object.
