AP Energy

Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated as the product of the force and the distance moved in the direction of the force.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as the product of mass, gravitational acceleration, and height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as 1/2 times the mass of the object times the square of its velocity.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the area under a force vs. distance graph?

Back

The area under a force vs. distance graph represents the work done on an object.

Front

What happens to kinetic energy when an object speeds up?

Back

When an object speeds up, its kinetic energy increases because kinetic energy is proportional to the square of its velocity.

Front

What is an ideal spring?

Back

An ideal spring is a theoretical spring that follows Hooke's Law perfectly, meaning the force exerted by the spring is directly proportional to its extension or compression.

Front

What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is proportional to the distance it is stretched or compressed, expressed as F = kx, where k is the spring constant and x is the displacement.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all individual forces and their directions.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through air, often increasing with speed.
