Laws of motion

Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

State Newton's First Law.

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 it mean for forces to be balanced?

Back

Balanced forces result in no change in motion; the object remains at rest or continues to move at a constant velocity.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion; the object accelerates in the direction of the net force.

Front

If two skaters push off each other, what can be said about their velocities if one has a smaller mass?

Back

The skater with the smaller mass will have a greater velocity than the skater with the larger mass.

Front

According to Newton's Third Law, what happens for every action?

Back

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

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
