Understanding Kinetic Energy

What is kinetic energy dependent on?

• Mass and speed

• Mass and volume

• Speed and temperature

• Volume and temperature

What is the formula for calculating kinetic energy?

• KE = 1/2 mv²

• KE = mv

• KE = 1/2 mv

• KE = mv²

How does mass affect kinetic energy?

• Greater mass results in more kinetic energy at the same speed

• Greater mass results in less kinetic energy at the same speed

• Mass does not affect kinetic energy

• Mass affects kinetic energy only at high speeds

What happens to kinetic energy if the speed of an object is doubled?

• It becomes four times greater

• It doubles

• It remains the same

• It becomes half

Why do engineers consider mass and speed when designing vehicles?

• To ensure safety and efficiency

• To increase the weight of the vehicle

• To reduce the cost of production

• To make vehicles faster
