Potential and Kinetic Energy – My Academy

03 January

Greta drops a particularly large and bouncy lemon (mass of 200g) from a height of 8m and notices that it loses 20% of its energy to the ground after every bounce. What is the total distance the lemon has travelled after coming into contact with the ground for the third time?

Potential and Kinetic Energy Kinetic Energy is the energy of motion. If something is moving at any non-zero speed, it has kinetic energy. If an object is moving in one direction and then changes to go back the same way …

In the second plan she makes she makes sure that the weight and speed mean that the rollercoaster car has kinetic energy of 3125 J when it approaches the first peak. How many peaks will it be able to clear with that amount of kinetic energy?

Greta moves on from flinging fruit and sketches a rollercoaster plan. The roller coaster pauses momentarily before it starts its drop down 7 m. If it weighs 10kg what is the potential energy at this point?

Greta took to other fruit to investigate energy. She grabbed a guava and threw it straight up. It reached a point 8.6 m directly above her before coming back down. What is the kinetic energy of the guava at its peak if it weighs 500g?

Greta first dropped a watermelon off a building to test that gravity was still working. If the watermelon was going at 20 m/s when it hit the ground and weighed 2 kg, how much kinetic energy was there?
