5P14 Predict Motion: Three Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.

Front

What happens when a skater pushes another skater?

Back

The skater who pushes moves backward due to Newton's 3rd Law of Motion.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked is an example of an unbalanced force acting on it.

Front

How does gravity affect motion?

Back

Gravity pulls objects toward the Earth, affecting their motion.

Front

What is the relationship between mass and acceleration?

Back

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

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.
