Velocity is a combination of...

Acceleration is...

The phrase "balanced forces" means?

• The speed and weight are the same

• The object is good at balancing on one foot

• The object doesn't move

• No motion and the net force on the object is 0

What is inertia?

Newton's First Law of Motion states...

• If an apple falls, there is gravity

• For every action there is an equal and opposite reaction

• An object at rest stays at rest; an object in motion maintains speed and direction unless changed by a force

• A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate

"Unbalanced forces" means...

• Net force is not equal to 0 and there is motion

• The speed and weight are not the same

• Net force equals 0 and the object doesn't move

• It is not good at balancing on one foot
