Unit 4 Motion and Energy

mass

• the amount of matter in an object
• a push or pull on an object
• a force which is applied to an object by a person or another object
• the action or process of moving or changing position

slope

• the measure of the steepness of a line
• the change of velocity of an object (direction and/or speed)
• a special type of frictional force that acts upon objects as they travel through the air.
• the support force exerted upon an object that is in contact with another stable object

friction

• the resistance that one surface or object encounters when moving over another.
• the support force exerted upon an object that is in contact with another stable object
• the rate at which an object moves
• the energy an object has due to its motion

kinetic energy

• the energy an object has due to its motion
• a force which is applied to an object by a person or another object
• the measure of the steepness of a line
• the resistance that one surface or object encounters when moving over another.

potential energy

• the energy an object can have because of its position or condition
• the speed of an object in a particular direction
• the energy an object has due to its motion
• the change of velocity of an object (direction and/or speed)

force

• a push or pull on an object
• the rate at which an object moves
• the resistance that one surface or object encounters when moving over another.
• the change of velocity of an object (direction and/or speed)

applied force

• a force which is applied to an object by a person or another object
• the energy an object has due to its motion
• an object at rest will stay at rest and an object in motion will stay in motion, unless acted upon by an outside force
• the measure of the steepness of a line

normal force

• the support force exerted upon an object that is in contact with another stable object
• the energy an object can have because of its position or condition
• the energy an object can have because of its position or condition
• the speed of an object in a particular direction

air resistance force

• a special type of frictional force that acts upon objects as they travel through the air.
• the speed of an object in a particular direction
• the support force exerted upon an object that is in contact with another stable object
• the amount of matter in an object

motion

• the action or process of moving or changing position
• an object at rest will stay at rest and an object in motion will stay in motion, unless acted upon by an outside force
• the amount of matter in an object
• a push or pull on an object
