100

What is the formula for calculating SPEED?

Distance / Time

200

Calculate the FORCE of a 250 kg motorcycle that accelerates 10 m/s².

2,500 N

300

What is the term used to describe a push or a pull on an object?

Force

400

What is the definition of a balanced force?

Equal forces; an object's motion will not change because the net force is zero

500

Newton's 1st Law

2

100

What terms describes an object's tendency to resist a change in motion?

Inertia

200

Newton's 3rd Law

300

Calculate the SPEED of a train that traveled 600 miles in 5 hours.

120 miles/hour

400

What is the force that pulls all objects that have mass toward one another?

Gravity

500

What is net force?

The overall force exerted on an object.

3

100

What term describes the resistance that one surface or object encounters when moving over another?

Friction

200

What is the definition of an unbalanced force?

Unequal forces; an object's motion will change because the net force is NOT zero

300

What term describes speed in a given direction?

Velocity

400

What term describes the rate of change of velocity (speeding up, slowing down, or changing direction)?

Acceleration

500
