Laws Of Motion

Front

What is the equation for force?

Back

F = mass × acceleration

Front

A change in velocity over time is called ___________.

Back

acceleration

Front

Calculate the force used on a 0.2 kg golf ball that accelerates at 20 m/s².

Back

4 N

Front

If a net force acts on a moving object in the direction that the object is moving, the object will slow down. True or False?

Back

False

Front

What is the force exerted by a 20 kg bike accelerating at 10 m/s²?

Back

200 Newtons

Front

Define Newton's 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 is inertia?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What does acceleration depend on?

Back

The net force acting on an object and the mass of the object.

Front

State the formula for calculating acceleration.

Back

Acceleration (a) = (Final velocity - Initial velocity) / Time
