Mason, Aria, and Emma are studying different forms of kinetic energy. They came across a few examples. Can you help them identify which of these are forms of kinetic energy?

• Mason's example of molecular motion

• Aria's example of heat

• Emma's example of a pendulum at its highest point

• Their example of running

Charlotte is driving an 800 kg car at a speed of 20 m/s. Suddenly, a cat crosses the road and she applies a net force of 200 N to the car causing it to accelerate. Aria and Harper, who are physics students, decide to calculate the kinetic energy of the car before Charlotte began to accelerate. What is the kinetic energy they calculated?

• 16000J

• 320000J

• 160000J

• 156800J

Benjamin and Anika are participating in a race. Rohan observes that as

• Benjamin and Anika's speed and mass increase, their kinetic energy also increases

• Benjamin and Anika's height and mass increase, their kinetic energy also increases

• Benjamin and Anika's potential energy increases, their kinetic energy also increases

• Benjamin and Anika's kinetic energy increases, their kinetic energy also increases

Noah and Abigail are studying physics. They are discussing the relationship between an object's mass and speed to its kinetic energy. Which two statements correctly relate the mass and the speed of an object to its kinetic energy, considering their discussion?

• If Noah doubles the speed of his bicycle, the kinetic energy will also double

• If Abigail doubles the speed of her car, the kinetic energy will more than double

• If Arjun doubles the mass of his skateboard, the kinetic energy will double

• If Noah doubles the mass of his bicycle, the kinetic energy will more than double
