Forces + Motion Vocabulary BEVERLY HILLS ELEMENTARY 5 TH GRADE

Forces A PUSH or PULL Measured in NEWTONS

Unbalanced Force When in size two forces acting on an object are not equal

Balanced Force Equal forces acting on one objects in opposite directions Dow not change the objects motion

Gravity Earth’s gravity is what keeps us on the ground and what makes objects fall Pulls objects downward

Gravitational Pull The pull that keeps us on the ground. Anything that has mass has a gravitational pull The amount of gravitation pull depends on the mass of the object (the more mass the bigger a pull)

Friction A force that is acting in the opposite direction of the motion of the object It will slow the object down Anytime two objects rub against each other they cause frication EX: The box they boy is pushing is rubbing against the floor creating friction

Acceleration Increase in speed

Deceleration Decrease in speed

Speed Measurement of how fast an object moves from one point to another

Constant Speed Going at the same speed, not getting faster and not getting slower

Distance How far an object traveled Can be measured in miles, kilometers (km), meters (m), etc.

Initial Position/ Reference Point The start position of an object (initial means beginning)

Velocity How fast an object is moving in a certain direction

Mass Measurement of how much matter is in an object (measured in kilograms = kg) Mass = how much matter is inside an object

Motion Being moved

Position Where an object is

Momentum The strength or force that something has when it is moving

Exerted To put forth as strength EX: He exerted force to open the jar

Increasing/Decreasing Increasing=Becoming greater Decreasing= Becoming less

Newtons What we measure force in

Inertia Tendency of a body or object to resist a change in motion or rest.

Compass Instrument with a magnetic pointer that will show the direction of North

X-Axis Horizontal axis on a graph (left to right)

Y-Axis Vertical line on a graph (up and down)
