Physical Science

A push or a pull

• gravity

• motion

• friction

• force

Net Force

• the sum of all the forces acting on an object

• a push or a pull

• forces that oppose each other

• the amount of gravity acting on an object

Two forces acting in opposite directions on an object, and equal in size

There is no acceleration

• balanced force

• net force

• unbalanced force

• what is a force???

friction

• the gravity acting on an object

• forces that work together to help an object move more easily

• the force that opposes the sliding motion of two surfaces that are touching each other

• the force that works in the same direction as two surfaces that are touching each other

a region of space that has a physical quantity at every point

• mass

• field

• cube

• earth

an attractive force between any two objects that depends on the masses of the objects and the distance between them

• net force

• field

• gravity

• magnetic

inertia

• an attractive force between any two objects

• the tendency of an object to resist any change in its motion

• a region of space that has physical quantity (such as a force)

• the push or pull on an object

the gravitational force that is exerted on an object

• weight

• mass

• force

• friction

force that opposes the motion of objects that move through the air

• sliding friction

• aerodynamics

• rolling friction

• air resistance

the maximum speed an object will reach when falling through a substance

• initial velocity

• initial force

• terminal acceleration

• terminal velocity
