2 cards from this section. Quick, good the night before a test.
What is kinetic energy?
Think about objects that are moving.
What is the formula for kinetic energy?
Remember the relationship of mass and speed.
What is kinetic energy dependent on?
Refer to the formula KE = 1/2 mv².
True or False: Kinetic energy can be converted to other forms of energy.
Think about how wind energy is converted.
A roller coaster car with a mass of 500 kg climbs a hill and reaches a height of 30 m. Calculate its potential energy at the top, then determine its kinetic energy at the bottom after it descends without friction.
Consider conservation of energy principles.
Evaluate the effect of doubling the speed of an object on its kinetic energy. If an object's initial kinetic energy is 100 J, what will it be when the speed is doubled?
Think about how speed affects energy calculations.
