An object’s tendency to remain at rest or in motion is

• inertia
• air resistance
• friction
• gravity

Forces that are in opposition to object that are falling

• inertia
• air resistance
• friction
• gravity

Resistance that an object encounter when moving over another object

• inertia
• air resistance
• friction
• gravity

Attracts objects toward the center of a larger mass

• inertia
• air resistance
• friction
• gravity

How does friction affect motion?

• It makes object slow down
• converts kinetic energy to thermal energy
• prevents objects from moving
• all of the above

How does gravity affect motion?

• Pulls objects down
• Pulls objects up
• make objects float
• moves objects stick to other objects
