Ocean Powered - Lesson 2

Front

What happens to the energy of an object when its mass doubles?

Back

The energy doubles (x2).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What happens to the energy of an object when its speed doubles?

Back

The energy quadruples (x4).

Front

What pattern is observed as an object's mass increases?

Back

An increase in kinetic energy.

Front

What two factors determine the amount of energy an object has?

Back

Mass and speed.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * speed (v)^2.

Front

How does increasing speed affect kinetic energy?

Back

Increasing speed increases kinetic energy exponentially.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases linearly with mass.

Front

What is energy conservation?

Back

Energy conservation is the principle that energy cannot be created or destroyed, only transformed.
