Motion

Front

A change in the position of an object over time from a reference point.

Back

Newton's Third Law

Front

For every action there is an equal and opposite reaction

Back

Magnitude

Front

A scalar quantity

Back

Example of velocity

Front

Nemo swims 37 m/s South to Wallaby Way in Australia.

Back

If an object is moving eastward and slowing down, then the direction of its velocity vector is

Front

East

Back

Newton's Second Law Equation

Front

Force = mass x acceleration

Back

unbalanced forces

Front

Forces that cause a change in the motion of an object

Back

If an object is moving northward and slowing down, then the direction of its acceleration vector is

Front

South

Back

Example of speed

Front

Nemo swims 58 m/s

Back

Newton's Second Law

Front

The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

Back

action-reaction forces

Front

pair of forces involved in an interaction that are equal in magnitude and opposite in direction

Back

Inertia

Front

The tendency of an object to resist a change in motion. Inertia depends on mass.

Back

Velocity

Front

speed of an object and its direction of motion; changes when speed, direction or both changes

Back

balanced forces

Front

Equal forces acting on an object in opposite directions

Back

Mass

Front

the amount of matter in an object

Back

Speed

Front

the distance traveled by an object in a given amount of time.

Back

distance

Front

the amount traveled from a certain spot.

Back

displacement

Front

the total distance traveled by an object regardless of direction from start to finish

Back

vector

Front

An quantity that has a magnitude and direction

Back

Acceleration

Front

Change in velocity. Can be a change in direction, positive (speeding up) or negative (slowing down).

Back

If an object is moving eastward and slowing down, then the direction of its acceleration vector is

Front

West

Back

Newton's First Law

Front

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Back

Force

Front

a push or pull on an object

Back
