Force and Motion

Force is

• the same as mass
• a push or a pull
• the weight of an object
• gravity

Gravity is an example of

• mass
• weight
• force
• motion

Weight is

• the gravity of an object
• the mass of an object
• the size of an object
• the height of an object

Mass is

• the weight of an object
• the force of an object
• the gravity of an object
• The matter of an object (atoms and molecules)

The gravity of an object is dependent upon its

• distance and mass
• weight and distance
• mass and weight
• distance and force

If an object's mass increases its gravity

• decreases
• stays the same
• increases
• is nothing

The following is an example of a net force

• a ball dropping
• a magnet attracting metal
• clay sinking in water
• throwing a basketball

A contact force is when the objects

• do not touch
• touch
• float in the air
• burn in a flame

A non-contact force is when the objects

• burn 
• float
• touch each other
• do not touch each other

An example of a contact force is

• magnetism
• gravity
• buoyancy
• static electricity
