What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What happens to momentum when the speed of an object is tripled?

Back

The momentum triples because momentum is directly proportional to velocity.

Front

What is the law of conservation of momentum?

Back

The law states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is a nonrenewable resource?

Back

A nonrenewable resource is a natural resource that cannot be replenished at the same rate it is consumed, such as oil and coal.

Front

Why is oil considered a nonrenewable resource?

Back

Oil is considered nonrenewable because it is consumed faster than it can be naturally replaced.

Front

What are renewable energy sources?

Back

Renewable energy sources are energy sources that can be replenished naturally, such as solar, wind, and hydroelectric power.

Front

What is the main source of energy for the Earth?

Back

The main source of energy for the Earth is the Sun, which provides heat and light energy.

Front

What is the difference between renewable and nonrenewable energy sources?

Back

Renewable energy sources can be replenished naturally, while nonrenewable sources are finite and will eventually run out.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv².
