ou drop a golf ball from a height of 1.0 m above the ground. It hits the ground and returns to a height of 0.5 m. Your friend makes the following argument: “The impulse Earth imparts to the golf ball as it falls must be larger than the impulse the ground imparts when the ball bounces because the time interval over which Earth exerts a force on the ball is much larger than the time interval over which the ground exerts a force on the ball.” Draw one or more momentum bar charts and use them to explain either your friend is right or wrong.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
