work
What is work
when a force moves something over a distance
What is potential energy?
stored energy in an object
What is motion?
When an objects position changes
What is applied force?
The force put on an object, a push
What is a collision?
happens when one object comes in contact with another object
Where did energy come from?
God created the universe and the energy in it
What is kinetic energy?
energy that an object has due to motion
What is speed?
measurement of how fast an objects position changes in a given amount of time
When you hear a block hit the floor, that is what type of energy
sound energy
Alec kicks the football. There is a collision between Alec's foot and the football. How is the energy transferred during the collision?
The hard kick transfers kinetic energy to the ball
When tying your shoes are you doing work?
yes the boy is producing force on the shoe strings
What is the relationship between the amount of stretch and the distance the rubberband traveled?
The more stretch the farther the rubberband travels
What is the cause?
What is effect?
Cause-tells why something happened
Effect-tells why what happened
Does an objects weight affect the objects kinetic energy?
yes the heavier weight means more kinetic energy
How does energy transfer when you turn on a drone?
Electrical energy is stored in a battery, then the battery is turned on and it is battery energy, as it goes in motion there is kinetic energy and the sound of blades turning is sound energy
Name 5 types of energy?
light, sound, battery, electricity. machine energy, sun, human energy
Felix rides his bicycle downhill to meet his friend. How does energy change from one to another?
Potential energy changes to kinetic energy as Felix rides downhill
How is motion and energy related?
Motion happens when energy is used
Energy is the ability to do work or cause change
Motion when something moves
How does speed affect an objects kinetic energy?
The faster the speed of an object the more the kinetic energy
How does energy transfer in a car collision?
When a moving car hits a car that is still, the still car will move forward with motion. The heavier the car or faster the car is moving will determine how far the hit car will move.
The ability to do work is force
True or False
false
Mallory pushed a marble down the slope of the driveway. How did that change the marble's energy?
The applied force to the marble increases its motion which increases its kinetic energy
A car and a train travel at the same rate of speed. Which one has more kinetic energy?
Train because it weighs more
In a flashlight the electrical energy from the battery changes into____________energy to turn on the bulb.
light
On a pool table what happens before, during, after the white ball is hit and collides with the other balls?
Before- The cue ball has kinetic energy and moves toward the other balls
During- The cue ball transfers kinetic energy to the other balls
After- The cue ball moves in a different direction and moves the other balls.
