Vocabulary
The ability to do work is ________.
Energy
A) The applied force to the marble decreases its weight, which increases its kinetic energy.
B) The applied force to the marble increases its motion, which decreases its kinetic energy.
C) The applied force to the marble increases its motion, which increases kinetic energy.
C
The horse uses kinetic energy as a result of running through the pasture. The italicized part of the sentence is the _____.
A) Cause
B) Effect
B) Effect
The electrical charge from a battery changes into light energy to turn on the lantern bulb. Why is this an example of energy transfer?
It shows a change in energy from one form to another.
Ash has a bat and is ready to hit the softball. She hits the softball with the bat, and the softball sails toward the outfield. Before the collision, the bat has kinetic energy and moves toward the softball.
What happens DURING the collision? (use the words kinetic energy, transfer, and sound energy in your answer)
During the collision, the bat transfers kinetic energy to the softball. Some of the energy becomes sound energy.
A skier at the top of a hill has ________ energy.
Potential Energy
Remi threw a baseball and a small rubber ball with the same applied force at the tower of blocks. Which ball will knock down more blocks? AND WHY?
Baseball - - Its weight gives it more kinetic energy to knock down more blocks.
The wagon has potential energy because it is at the top of a hill. The italicized part of the sentence is the _______.
A) Cause
B) Effect
A) Cause
There is a collision between a soccer ball and a player's foot. How is energy transferred during the collision?
They can apply force to push the pedals and cause the bikes to increase in motion. As the motion increases, the bike's kinetic energy increases.
The skier sliding down the end of the hill is called ________ energy.
Kinetic Energy
Arnold kicked a soccer ball. There is a collision between Arnold's foot and the soccer. How is the energy transferred during the collision?
The hard kick transfers kinetic energy to the ball.
The book resting on the edge of the table has potential energy because the book could fall. The italicized part of the sentence is the ________.
A) Cause
B) Effect
B) Effect
How is a flying drone an example of energy transfer?
River balances a cue stick on the pool table. He hits the cue ball. The cue ball moves toward the group of balls.
What happens BEFORE the collision?
The cue ball has kinetic energy and moves toward the other balls.
True or False:
The stored energy in an object is potential energy.
TRUE
Xavier pushed a marble down the slope of the driveway. What is true about the marble?
A) The applied force is greater than the force of the marble.
B) The force of friction is greater than the applied force.
C) The force of gravity pushed the marble up the slope.
A) The applied force is greater than the force of the marble.
The book falls off the table. As the book falls, what happens?
(use the words: potential and kinetic energy in your answer)
Potential energy changes to kinetic energy as the book falls.
When electrical energy transfers from a battery to a light bulb, the electrical energy changes into ______ energy.
Light
River balances a cue stick on the pool table. He hits the cue ball. The cue ball moves toward the group of balls.
What happens DURING the collision?
The cue ball transfers kinetic energy to the other balls.
True or False:
The energy that an object has due to its motion is its kinetic energy.
TRUE
A car and a train travel at the same rate of speed. Which one has more kinetic energy? AND WHY?
The train's weight gives it more kinetic energy.
Where does energy come from?
God created the universe and everything in it.
Kinetic
River balances a cue stick on the pool table. He hits the cue ball. The cue ball moves toward the group of balls.
What happens AFTER the collision?
The cue ball moves in a different direction than it was before.
