the person able to state rules that describe the effects of forces on the motion of objects

• Madam Curry

• Sir Isaac Newton

• Albert Einstein

• Orville Wright

Newton's first law of motion states...

• that an object in motion will stop motion unless an unbalanced net force acts on it.

• that an object in motion will stay in motion unless an unbalanced net force acts on it.

how far something has moved

• Distance

• Displacement

• Position

• Velocity

describes speed of motion when speed is changing; the total distance traveled divided by the total time of travel.

• speed

• instantaneous speed

• average speed

• constant speed
