1. Which of the following statements about speed and velocity is correct?

Only velocity includes the direction an object is traveling.

Velocity only describes an object’s rate of motion.

Speed describes how an object is changing its velocity.

Speed and velocity both describe how an object is speeding up.

Acceleration describes how an object’s velocity is changing. Which of the following scenarios provides the best example of an accelerating object?

A toy train traveling in a circle

A car driving at a constant speed

A book sitting on top of a high shelf

A toy boat floating in a bathtub

When a car goes around a corner at 20 mph, why do we say it accelerates?

The car is accelerating because it's changing direction

The car is accelerating because of the velocity is constant

The car accelerates because it's going 20 mph

Cars always accelerate when they are in motion

Which of these objects is NOT accelerating?

A hiker moving at the same speed for hours

A rollerblader heading downhill

What is the object doing from 10-12.5 seconds?

Returning to the starting position

Which graph is would represent a decrease in speed?

The object is not decreasing in speed in any of these graphs

When a car goes around a corner at 20 mph, why do we say it accelerates?

The car is accelerating because it's changing direction

The car is accelerating because of the velocity is constant

The car accelerates because it's going 20 mph

Cars always accelerate when they are in motion

sum of kinetic and potential energy

energy built up before being in motion

energy released in a chemical reaction

Explain what happens to the potential energy of a rock as it falls off the side of a cliff.

The potential energy decreases as the kinetic energy increases.

The kinetic energy decreases as the potential energy increases.

The kinetic energy decreases as the potential energy decreases.

The potential energy decreases as the kinetic energy decreases.

When riding a roller coaster, you go up and down many hills. As you get to the top of a roller coaster, what energy change is taking place.

Kinetic energy is changed into potential energy.

Potential energy is changed into kinetic energy.

Chemical energy is changed into heat energy.

Heat energy is changed into chemical energy.

Which is an example of potential energy?

the pulled back string on an archers's bow

a roller coaster speeding down a hill

releasing the strings on a guitar
