Newton's First Law States.......................

• Acceleration is produced when a force acts upon an object. 
• For every action, there is an equal and opposite reaction. 
• An object at rest, stays at rest; an object in motion stays in motion.

Motion occurs when......................

• the speed of an object changes. 
• an object's distance from another object changes. 
• there is an increase or decrease in an object's speed. 

Newton's Second Law states.........................

• that an object in motion, stays in motion; an object at rest stays at rest. 
• For every action there is an equal and opposite reaction.
• that acceleration occurs when a force acts upon an object. 

Average speed is calculated..............

• by dividing the total distance by the total time. 
• by dividing distance by time. 
• by multiplying mass and acceleration. 

What is acceleration?

• The speed and direction of an object's motion. 
• An increase or decrease in speed, or a change in direction. 
• The tendency of an object to resist change in its motion. 

A measurement of the amount of matter in an object. 

• Gravity
• Weight
• Mass
• Speed

• This is an example of Newton's First Law.
• This is an example of Newton's Second Law.
• This is an example of Newton's Third Law.

When an object rolls over a surface. 

• Sliding Friction 
• Rolling Friction 
• Fluid Friction 

Inertia........................

• is the tendency of an object to resist change in its motion.
• is an increase or decrease in an object's speed. 
• is the speed and direction of an object's motion. 

Newton's Third Law states that.......................

• an object at rest, stays at rest; an object in motion stays in motion. 
• acceleration occurs when a force is exerted on an object. 
• for every action, there is an equal and oppostite reaction.
