Force and Motion

2. ______________________ is any push or pull on an object.

• force

• mass

• gravity

• air resistance

Starting point you choose to describe the location (or position) of an object.

• Reference Point

• Relative Motion

• Acceleration

• Dimension

Overall force acting on an object when all of the forces on it are combined.

• Balanced force

• Contact force

• Net force

• Force

A force that resists motion when 2 surfaces rub together.

• Friction

• Gravity

• Force

• Balanced force

What is the speed formula?

• d = s*t

• s= time/distance

• d= speed/time

• s = distance/time

What units is Force measured in?

• Grams

• Miles

• Hours

• Newtons

The FIRST part of Newton's 1st law states:

• An object at rest will stay at rest

• An object in motion will stay in motion

• An object at rest will stay in motion

• An object in motion will stay at rest

The SECOND part of Newton's 1st law states:

• An object at rest will stay at rest

• An object in motion will stay in motion

• An object at rest will stay in motion

• An object in motion will stay at rest

The THIRD part of Newton's 1st law states things will move the way they are moving right now...:

• UNLESS acted upon by an inside force

• UNLESS unchanged by an outside force

• UNLESS acted upon by a balanced force

• UNLESS acted upon by an outside force

What is a force that causes an object to start moving, stop moving, or change direction

• Acceleration

• Unbalanced Force

• Balanced Force

• Inertia
