AP Physics 1: Work and Kinetic Energy

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) is given by the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How does kinetic energy change with velocity?

Back

Kinetic energy increases with the square of the velocity. If the velocity is tripled, the kinetic energy increases by a factor of 9.

Front

What is the definition of work in physics?

Back

Work is defined as the process of energy transfer that occurs when an object is moved over a distance by an external force.

Front

Is work a scalar or vector quantity?

Back

Work is a scalar quantity.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is potential energy?

Back

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

Front

What is the unit of work in the International System of Units (SI)?

Back

The unit of work is the Joule (J).

Front

What does a force vs. position graph represent?

Back

A force vs. position graph shows the relationship between the force applied to an object and the distance it moves, allowing calculation of work done.

Front

How do you calculate work from a force vs. position graph?

Back

The work done is equal to the area under the force vs. position graph.

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.
