Force and Motion 1

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is motion?

Back

Motion is the change in an object's position over time.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the Earth.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is friction?

Back

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

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when one person pushes a swing harder than another, causing it to move.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, they cause a change in the motion of an object.

Front

What is the role of energy in motion?

Back

Energy is required to cause motion; it can be transformed from one form to another.
