Why is energy considered essential in our daily lives?

How does thermal energy work, and what is an example of its application?

In what ways is radiant energy different from thermal energy?

Why is radiant energy important for plants?

What would happen if we removed all energy from our lives?

Kinetic energy is calculated by multiplying the mass of an object by its velocity squared.

• True

• False

Gravitational potential energy depends on the object's velocity.

• True

• False

If an object has zero velocity, it has no kinetic energy.

• True

• False

Kinetic energy can be transferred from one object to another, but gravitational potential energy cannot.

• True

• False

The ground always represents zero height when measuring gravitational potential energy.

• True

• False
