What type of energy is associated with the motion of an object?
Kinetic Energy
Give an example of a situation where an object has high potential energy based on an activity we did in class. Be descriptive.
Answers may include: A rubber band stretcged to its maximum of 20cm; Holding a tennis ball from the highest point, 2m; Placing the marble at the top of the halfpipe.
What is the relationship between potential energy and height?
The higher the height of the object, the more potential energy it has.
What are the three states of matter?
Solid, Liquid, Gas
What is the term for the energy stored in an object?
Potential Energy
Describe a scenario where an object has kinetic energy.
Answers may include: a car moving, the marble rolling down the ramp, the tennis ball right before it hits the ground.
Explain how mass effects potential energy.
The more mass an object has, the more potential energy it has.
What process do plants use it make food?
Photosynthesis
What do we call the energy stored in a stretched or compressed spring?
Elastic Potential Energy
What happens to the potential energy of a pendulum as it swings from its highest point to its lowest point?
Answer: Potential energy is converted into kinetic energy OR potential energy decreases and kinetic energy increases.
What is the primary unit of measurement for energy?
Joule (J)
What is a group of lions called?
A pride.
What is the term for energy that is transferred through forces acting at a distance, such as gravity?
Gravitational Potential Enegy
What happens to the energy when a ball is thrown into the air? Include a model with your answer.
The potential energy of the system increases as the ball rises.
Name three forms of energy.
Chemical, magnetic, elastic, electric, gravitational, nuclear, thermal, sound
An astronomical unit (AU) is a unit of measurement used for comparing distances in space, what is this unit based off of?
The average distance from the Earth to the sun.
What is the law that states energy cannot be created or destroyed, only transformed?
The Law of Conservation of Energy
Using your whiteboard, draw a model of an apple falling from a tree. Label: Where the apple has max PE; where the apple has max KE, where the apple has 50% PE and 50% KE
Max PE when the apple is hanging in the tree, 50/50 halfway down; max KE right before it hits the ground.
What relationship do potential and kinetic energy have within a system?
An inverse relationship, when one increases the other decreases.
How deep can some squid dive (in meters)? Closest answer gets the points.
About 3050 meters.
