Force and Motion

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that do not cancel each other out and will change the motion of an object.

Front

What does Newton's First Law state about an object at rest?

Back

According to Newton's First Law, an object at rest will remain at rest unless a force acts on it.

Front

What happens to the speed of an object if you increase the force pushing on it?

Back

If you increase the force pushing on an object, its speed will increase.

Front

What can unbalanced forces cause?

Back

Unbalanced forces can cause the speed to increase, decrease, or change the direction of an object.

Front

What does Newton's First Law state about an object in motion?

Back

According to Newton's First Law, an object in motion will remain in motion unless a force acts on it.

Front

What is the definition of force?

Back

Force is a push or pull on an object that can cause it to change its motion.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater the acceleration it will experience.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.
