Energy Unit Pretest

A fossil fuel is a renewable resource formed from the remains of an ancient organism

• True

• False

Answer explanation

This is true! The fuel we use comes from ancient plants and animals!

Mechanical energy is the sum of an object’s potential and kinetic energy

• True

• False

A renewable resource forms at a rate that is much slower than the rate in which the resource is used

• True

• False

Answer explanation

This is false. A renewable resource is one that is made at the same speed that it is use. In other words, it is renewed before it runs out!

The kinetic theory of matter states that all of the particles that make up matter are in a fixed (stationary) position

• True

• False

Answer explanation

False! All particles are always moving!

Heat is the energy transferred from an object at a higher temperature to an object at a lower temperature

• True

• False

How could two objects have the same temperature but different thermal energies?

• one object could have more heat

• one object could have more calories

• one object could have more particles and less total kinetic energy

• one object could have more particles and greater total kinetic energy

Answer explanation

Thermal energy measures all the total kinetic energy an object has.

The ocean holds so much water that it has the greatest kinetic energy out of all liquids, even when it is cold, because each atom in the ocean has energy! When you add them all up, you have thermal energy
