The tendency for an object to resist a change in motion is called

• Inertia
• Mass
• Velocity
• Force

When more than one force acts on an object...

• only the larger force acts on it.
• only the smaller force acts on it
• the two forces combine to give a net force.
• it stays still.

Inertia depends on an objects

• mass.
• speed.
• velocity.
• force.

If an object is in motion and a force is applied, it will

• Change speed or direction
• Speed up.
• Slow down.
• Change direction.

When a stationary object is not acellerating

• the forces on it are balanced.
• gravity is not affecting it.
• there is a net force acting on it.
• its mass is changing

If the same force is applied to two objects with different masses...

• The smaller object will accelerate more.
• The larger object will accelerate more.
• The will both accelerate at the same speed. 
• The masses will cancel out and there will be no net force.
