Speed!
100
How fast an object is traveling over a given distance.
What is speed?
100
The less mass an object has, the less of this is needed to move it.
What is force?
100
A force that that pulls objects to the center of the earth.
What is gravity?
100
An example of this force can be observed during a kickball game when the ball is pitched, but the force between the ball and the ground makes the ball stop before reaching the kicker.
What is friction?
100

What is the formula for speed?

Speed= distance divided by time

200

A change in speed or direction

Acceleration

200
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an ____________ force.
What is unbalanced?
200
When two objects rub together, they create this force.
What is friction?
200

If a car travels 100 miles in 2 hours what is its speed

50 mph

200

If a car goes 20 miles in 2 hours what is its speed?

10 mph

300

A change in position over time is called 

Motion

300
What does F=MA stand for?
Force=Mass x Acceleration
300
A moving object will do this when friction is increased.
What is slow down or stop?
300

What scientist developed the 3 laws of motion?

Isaac Newton

300

In 5 hours a car goes 30 miles. What is its speed?

6 mph

400
To find this use the formula distance/time (d divided by t)
What is speed?
400
If equal forces are balanced on an object, then this will happen with the object.
What is NO movement?
400
This is the result when weight is added to a vehicle and the force is not increased.
What is slow down or reduce speed?
400

What unit is force measured in?

Newtons

400

True or false: To calculate speed we do time divided by distance

False

500
In order to start something moving, this must be applied to the object.
What is an unbalanced force?
500
For every action, there is an _____________ and ___________ reaction.
What is equal and opposite
500

A push or pull is called this

A force

500

If you push harder on a swing it moves faster because of this law.

Newton's second law

500

If it takes me 50 hours to drive 250 miles how long does it take

5 mph
