Speed, Velocity, Energy
Friction
Gravity
Motion and Force
100
Any push or pull
What is force?
100
Divide the distance traveled by the amount of time the object took to travel that distance.
How do you figure out speed?
100
A force that acts when two surfaces rub together.
What is friction?
100
A force which makes objects pull toward each other.
What is gravity?
100
A book, not a truck.
Which will require less force to move?
200
The rate at which an object changes position.
What is speed?
200
Starting, speeding up, or slowing down.
What is an acceleration?
200
Objects with more mass.
What can create more friction?
200
Newton
What unit is used to measure the force of gravity?
200
A truck, not a book.
Which will require more force to move?
300
Combines both speed and direction.
What is velocity?
300
A yo-yo that is resting on the tip of your fingers.
What is potential energy?
300
A smooth surface.
What can reduce friction?
300
Two objects located far apart from each other have this kind of pull by gravity.
What is less gravity?
300
When you pluck a guitar string, it has this kind of movement.
What is vibration?
400
The force that makes objects pull toward each other.
What is gravity?
400
A yo-yo traveling up and down on its string.
What is kinetic energy?
400
This will slow or stop an object from moving.
What is friction?
400
Two objects with larger mass will have this kind of pull by gravity.
What is more gravity?
400
The object will stay in place and not move.
What happens when an object is pulled on by equal forces?
500
The change in one object's position compared with another object's position.
What is relative motion?
500
The resistance an object has to any change in its motion.
What is inertia?
500
Oil or wax
What can reduce friction?
500
A spring scale.
What instrument is used to measure the force of gravity?
500
The moving object will keep moving in the same direction.
What happens when balanced forces are applied to a moving object?
