AP Physics 1 Semester 1 Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula KE = 0.5 * m * v^2, where m is mass and v is 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. The total energy in a closed system remains constant.

Front

Define impulse in physics.

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is calculated as Impulse = Force * Time.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity and is calculated using the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

Explain the relationship between work and energy.

Back

Work is done when a force causes an object to move. It is a transfer of energy and is calculated using the formula Work = Force * Distance * cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred. It is calculated using the formula Power = Work / Time.

Front

What is the difference between work and power?

Back

Work is the total energy transferred, while power is the rate at which that energy is transferred. Power takes into account the time it takes to complete a task.

Front

How does height affect potential energy?

Back

Potential energy increases with height. As an object's height increases, its potential energy increases because it has the potential to do more work due to gravity.

Front

What happens to kinetic energy during a collision?

Back

In a collision, kinetic energy can be transferred from one object to another. In elastic collisions, total kinetic energy is conserved, while in inelastic collisions, some kinetic energy is transformed into other forms of energy.
