Science Review Energy and Motion

What is energy?

• a type of kinetic energy that we can see with our eyes

• the motion of an object

• the ability to cause chganges in matter

• the energy an object has because of its position or condition

What is the difference between potential and kinetic energy?

• kinetic energy is energy that an object has based on its position and potential is a type of energy we can see with our eyes

• kinetic energy is the energy of motion whereas potential energy is the energy that an object has based on its position

• kinetic energy is the energy we can see with our eyes whereas potential energy is not

• kinetic energy is when energy is transforming matter whereas potential is when energy bends

What is thermal energy?

• the total kinetic energy of the particles that make up a substance and is measured using a thermometer

• the energy caused by the movement of electrical charges

What form of energy is in a battery?

• light energy

• qkinetic energy

• chemical energy

• electrical energy

Which has the LEAST amount of potential energy?

• a ball at the top of a hill;

• a rollercoaster going down a hill

• a child at the top of a slide

• a car parked in a parking lot

What form of energy can be absorbed, reflected or bent by different materials?

• sound

• electrical

• light

• mechanical

What forms of energy does this object give off?

• light energy and thermal energy

• light energy and sound energy

• light energy and electrical energy

• light energy and chemical energy

True or false: When an object's position changes, it is in motion.

• True

• False

True or False: To find an object's speed, you need to measure two things -- distance and time.

• True

• False

Which is not an example of energy causing motion?

• picking up a box

• holding a box
