Newton's Laws

Front

What does F=ma represent?

Back

Front

Friction is a force that acts in an ___________ direction of movement.

Back

opposite

Front

What is motion?

Back

Any change in an object or person's position.

Front

What does an unbalanced force mean for an object?

Back

It is changing its motion.

Front

Objects with greater _________ also have greater inertia.

Back

mass

Front

What is Newton's 1st 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 is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is Newton's 3rd law?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F=ma).

Front

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

Back

As mass increases, acceleration decreases if the force is constant.
