A train traveled for 4 hours and went 180 miles. What was the average speed of the train?
What is 45 miles per hour?
200
An objects distance changes from another object or reference point.
What is motion?
200
Changing directions is an example of this.
What is acceleration?
200
Why do stationary objects make good reference points?
What is because they do not move?

These two kinds of graphs can be used to analyze the motion of an accelerating object.
What are speed vs time graphs and distance vs time graphs
300
An ant went 2 meters in 10 seconds. What was the average speed of the ant?
What is 0.2 meters per second?
300
Speed in a specific direction.
What is velocity?
300
Potential energy that depends on height is called this.
What is gravitational potential energy?
300
This is the difference between average speed and instantaneous speed
What is average speed is overall speed over a distance and instantaneous speed is speed at a specific time?
300
These two factors effect the amount of kinetic energy.
What are mass and speed?
400
Mr. Matthews drives 600 miles in 30 hours. What is his average speed?
What is 20 miles per hour? (He better find the gas peddle!)
400
When objects slow down.
What is deceleration?
400
The equation for acceleration.
What acceleration = (final speed - initial speed) / time
400
This is the difference between speed and velocity.
What is direction? Speed is how fast an object is moving. Velocity is how fast an object is moving in a given direction.

You throw a ball in the air. This is the point at which the potential energy is the greatest.
What is right before it falls back down?
500
A car travels 85 km in the first hour of a trip. The car continues to travel for 2 more hours and travels 200 km. This is the average speed of the car during the trip.
What is 95 km/h?
500
If the speed of an object does not change, the object is traveling at this.
What is a constant speed?

According to this science law, energy can not be created or destroyed.
What is the law of conservation of energy?
500
These are the three ways acceleration can change.
What are speeding up, decelerating, and changing directions
500
This is a quantity that consists of moth a magnitude and a direction.
