Lesson: Kinetic Energy High School PhysicsPhysics
In this lesson, we will learn how to calculate the kinetic energy of objects of different masses, moving at different velocities.

How many times larger is the kinetic energy of a bullet of mass 0.005 kg that has a velocity of 500 m/s than the kinetic energy of a drone with a mass of 5 kg and a velocity of 5 m/s?
A motorboat at rest on a lake has a mass of 665 kg. The motorboat then accelerates until it has a kinetic energy of 340,480 J. When the motorboat has accelerated, at what rate does it move toward a stationary boat that is directly in front of it?
A hummingbird has a mass of 40 g. The hummingbird flies in a straight line between two flowers 18 m apart in a time of 12 s. What is the average kinetic energy of the hummingbird while flying between the flowers?
