KINETIC ENERGY

QuestionAnswer
Define kinetic energy. energy of motion of an object
List the two factors that determine kinetic energy: mass and velocity
Write the equation for finding kinetic energy: KE=1/2 mv^2
What is the kinetic energy of a 20.0 kg child running across a playground at a velocity of 2.0 m/s? (Ignore friction) 40.0 J
Explain how to determine the energy of motion for a car moving down the road. Energy of motion is kinetic energy. To determine the KE of the moving car, the speed (velocity) and the mass of the car would be needed.These values would be used in the equation to determine the KE of the car.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
