Physics: Potential and Kinetic Energy in Daily Life

A skateboarder waits at the top of a ramp before rolling down. Identify the main type of energy the skateboarder has at the top of the ramp and explain why.

A soccer ball is kicked across a field. Identify the main type of energy the moving ball has and explain why.

A book sits on the top shelf of a bookcase. How would the book's gravitational potential energy change if it were moved to a lower shelf?

A stretched rubber band is held between your fingers. What type of potential energy does it have, and what happens to that energy when you let go?

A student drops a pencil from a desk. Describe how the pencil's potential energy and kinetic energy change as it falls.

Two identical water bottles are sitting on shelves. Bottle A is on a shelf 1 meter above the floor. Bottle B is on a shelf 2 meters above the floor. Which bottle has more gravitational potential energy, and why?

A bicyclist pedals faster on a flat road. How does the bicyclist's kinetic energy change as speed increases?

A roller coaster car is moving down the first big hill. Explain how energy is changing from the top of the hill to the bottom.

A lunchbox and a backpack are both placed on the same table. The backpack has more mass than the lunchbox. Which object has more gravitational potential energy on the table, and why?

A car is parked at the top of a steep driveway. Later, it rolls down the driveway. Identify the main energy type before it starts moving and the main energy type while it is rolling.

A child pulls a toy car backward and lets it go so it races forward. The toy car has a spring inside. What energy changes happen in the toy car?

A basketball is held above the floor and then dropped. At what point does it have the greatest gravitational potential energy: when it is held high, halfway down, or just before it hits the floor? Explain your answer.

A bowling ball and a tennis ball roll at the same speed. Which one has more kinetic energy, and why?

A phone is charging on a desk, then it falls off the desk. Explain why the phone has potential energy before it falls and kinetic energy while it falls.
