Force and motion sj 2526

Front

Motion

Back

A change in an object’s position.

Front

Speed

Back

An object’s speed is determined by the distance an object traveled and how long it took to travel that distance.

Speed = distance/time

Front

velocity

Back

An object’s velocity  is determined by the distance an object traveled and how long it took to travel that distance and what direction the object traveled. (35m/s east)

Front

What is the difference between speed and velocity? 

Back

Speed only tells a distance and a time but velocity takes a speed and adds a direction.

Front

displacement

Back

An object’s displacement is the overall  change in an object's position, defined by its starting and ending points, not the entire path taken

Displacement includes direction 

Front

What is the difference between distance and displacement?

Back

An object’s displacement is the overall  change in an object's position, defined by its starting and ending points.

An object's distance is the entire path taken.

Front

Force

Back

Forces are push and pulls that cause object to move or to stop moving.

Front

distance

Back

An object’s distance is how far an object moved.

Front

Newton’s 1st law of motion

(also called law of inertia)

Back

A body (an object) in motion tends to stay in motion or a body at rest (not moving) tends to stay at rest unless acted upon by an outside force. 

Front

Speed = distance/time

Back
