Newton & Energy Vocabulary

What is potential energy?

• Energy that is stored and held in readiness

• The energy an object has due to its motion

• The speed of an object in a particular direction

• The force of air pushing against a moving object

What is kinetic energy?

• The energy an object has due to its motion

• The location of an object

• The amount of matter in an object

• The resistance one surface encounters when moving over another

What does the Law of Conservation of Energy state?

• Energy cannot be created or destroyed but can be changed from one form to another

• An object at rest stays at rest unless acted upon by an unbalanced force

• The acceleration of an object depends on the mass and the force applied

• When one object exerts a force on another, the second object exerts an equal force in the opposite direction

What is inertia?

• The tendency of an object to resist a change in motion

• The speed of an object in a particular direction

• The force of air pushing against a moving object

• The amount of matter in an object

What is displacement?

• Distance and direction of an object's change in position from the starting point

• The length of a path between two points

• Distance traveled per unit time

• The speed of an object in a particular direction

What is speed?

• Distance traveled per unit time

• The speed of an object in a particular direction

What is velocity?

• The speed of an object in a particular direction

• Distance traveled per unit time

• The amount of matter in an object

• The resistance one surface encounters when moving over another

What is mass?

• The amount of matter in an object

• The energy an object has due to its motion

• The location of an object

• The tendency of an object to resist a change in motion

What is force?

• A push or pull on an object

• The speed of an object in a particular direction

• The amount of matter in an object
