3 cards from this section. Quick, good the night before a test.
What is kinetic energy?
Think about moving objects in your surroundings.
Write down the formula for kinetic energy.
Remember it relates mass and velocity!
What is the formula for kinetic energy?
Remember it involves mass and the square of speed.
Does mass affect kinetic energy? (True/False)
Think about what happens when mass increases.
A cyclist and a car are both traveling at 25 m/s. If the car has a mass of 1500 kg and the bicycle has a mass of 20 kg, how do their kinetic energies compare?
Use the kinetic energy formula for both.
If a freight train having a mass of 500,000 kg is moving at 10 m/s, how much kinetic energy does it possess? How would its kinetic energy change if it were moving at 20 m/s?
Calculate using $KE = \\frac{1}{2}mv^2$.
