Force
This is a push or pull on an object
What is Force?
This describes how far an object moves in a certain amount of time.
What is speed
Energy of Motion
What is Kinetic Energy
Friction always works in this direction relative to motion
What is the opposite way
Gravity is this type of force between two masses
An attractive force
The unit used to measure force.
A straight, slanted line on a distance-time graph indicates this type of speed.
What is constant speed
Stored energy based on position or condition
What is potential energy
Friction between solid surfaces that are NOT moving past each other
What is static friction
The force that pulls objects toward Earth
What is Gravity?
This type of force requires physical contact between objects.
What is contact force
A change in an object's speed or direction is called this
What is acceleration
When a roller coaster climbs a hill, this type of energy increases
What is gravitational potential energy
Friction between surfaces that are sliding past each other
What is kinetic friction, or sliding friction
The amount of gravitation pull on an object determines this measurable quantity.
What is weight
When forces on an object are equal in size and opposite in direction, they are called this
What are balanced forces
An object will stay at rest or in motion unless acted on by an external force-this summarizes which law?
What is Newton's First Law of Motion
The law that states energy cannot be created or destroyed
What is the Law of Conservation of Energy
Rubbing your hands together produces this kind of energy due to friction
What is thermal energy
This famous scientist discovered that all objects fall at the same rate when there is no air resistance.
Who was Galileo
The net force when 50 N acts right and 30 N acts left
What is 20 Newtons to the right
The total distance is 120 meters, and time is 20 seconds. Calculate the speed.
What is 6 m/s?
A stretched rubber band is an example of this specific type of POTENTIAL energy
What is elastic potential energy
This type of friction occurs when an object moves through a fluid such as air or water
What is fluid friction (sometimes called drag)?
If mass increases, the force of gravity between two objects changes in this way
What is it increases
