Motion is described by an objects __________ and ________.
Direction and Speed
Name 3 types of force
Gravity, friction, elasticity, electricity, and magnetism
Stored energy is...
Potential Energy
The energy of motion is...
Kinetic Energy
In science, this is when two or more objects hit each other with force.
What is collision.
Examples of directions are...
Up, Down, Foward, Backwards, etc
What is the force that occurs when matter rubs against matter?
Friction
Which has more potential energy the clock, or poster hung on the bulletin board?
The clock
Which has more kinetic energy a fast ball thrown by Grady., or an underhanded pitch thrown by Mrs. Weis?
Fast ball by Tyler
This is the measure of how easy or hard it is to stop a moving object.
What is momentum.
Speed equals ________ _________ dived by ________ spent moving.
distance traveled, time
What force allowed Mr. Thode to throw a tennis ball make it pause mid air, and return to her?
Gravity
All ______ objects have kinetic energy.
Moving
This is the tendency for an object in motion to stay in motion and an object rest will stay at rest.
What is inertia?
What is the property of matter that causes it to resist an change of its motion in either speed or direction.
Inertia
When friction occurs so does ________.
heat
Where would a child have more potential energy at the top of a slide or at the bottom.
top
What is one time of the day that you use kinetic energy?
Example: gym, recess, or taking notes.
These two things are measured when describing velocity.
What is speed and direction?
Unless acted on by a force objects in ________ tend to stay in _______, and objects in _____ tend to stay in _____.
motion, motion, rest, rest
What is a push, or pull that causes an object to move, stop, or change speed or direction.
Force
Name three different objects in the room with potential energy, then order them from most potential energy to least.
Example: clock, a book on a desk, and a pencil on the floor.
Which point on a roller coaster would the kinetic energy be the highest.
At the bottom of the hill.
This is when energy is moved from one object to another in a collision.
What is energy transfer?
