Forces
What is a push or pull on an object?
Force
How far an object moves over a given time (eg the car moves 50 km/hour)
Speed
For every action there is an opposite and equal reaction
3rd Law of Motion
Energy that is in motion
Kinetic Energy
A force that slows the motion of objects by physically touching them
Friction
A force that results when objects are physically touching each other
Contact Force
the speed of an object in a certain direction
Velocity
An object stays in rest or in motion unless acted upon by an outside force
1st Law of Motion
Energy that has not been released yet
Potential Energy
Drag
When one force is stronger than the other, making the object move
Unbalanced force
Movement in any direction
Motion
The tendency of an object to stay at rest or in motion
Inertia
The higher an object is, the more ________ energy an object has
potential
What is the name of the substance used to reduce friction?
Lubricant
Gravity is an invisible force. Therefore it is a _________ force.
Non-Contact
A change in velocity
Acceleration
Acceleration depends on the mass and the applied force on an object
2nd Law of Motion
The amount of matter in an object
Mass
The more ___________ a parachute has, the more friction it will go against in the air, slowing it down.
Surface Area
A magnet holding a metal object in place is an example of a _________ force. (cannot say contact for this answer)
Balanced
When discussing the motion of an object, it is important to include the _________ and ___________
Direction and position
If you push a basketball down to the floor with more force, it will bounce back up higher. Which Law of Motion is the reason for this?
3rd Law of Motion
The measure of the force of gravity on an object
Weight
You move slower in water because of a type of friction called _______________ (drag will not count)
Water resistance
