What is Newton's 1st Law?

• For every action there is an opposite and equal reaction

• An object at rest will remain at rest. An object that is moving at constant speed will continue moving at constant speed unless acted upon by an unbalanced force

• The net force on an object is equal to the product of its acceleration and mass

• Treat others as you want to be treated

The net force on an object is equal to the product of its acceleration and its mass **Force = Mass x Acceleration**

• Newton's1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Balanced Forces

What is Newton's 3rd Law?

• For every action there is an equal and opposite reaction

• An object at rest will stay at rest unless acted upon by an unbalanced force

• The net force on an object is equal to the product of its acceleration and its mass

• Force=Mass x Acceleration

• the force that pulls things into the center of the earth

• a push or pull

• a unit of force

What is the friction that acts on objects that are not moving (ex: a desk sitting on the floor)?

• static friction

• sliding friction

• rolling friction

• fluid fricion

What occurs when an object rolls across a surface (ex: a computer cart on wheels)?

• static friction

• sliding friction

• rolling friction

• fluid friction
