Pre-AP Potential and Kinetic Energy

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of an object in motion.

Front

What is the formula for calculating potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

At what point is potential energy greatest in a vertical motion scenario?

Back

Potential energy is greatest at the highest point of the object's motion.

Front

How does potential energy change as an object is lifted higher?

Back

As an object is lifted higher, its potential energy increases due to the increase in height (h) in the formula PE = mgh.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases because kinetic energy is directly related to the square of its velocity.

Front

If a ball is thrown upwards, what happens to its potential and kinetic energy at the peak of its trajectory?

Back

At the peak of its trajectory, the ball has maximum potential energy and minimum kinetic energy.

Front

What is the relationship between potential energy and kinetic energy during free fall?

Back

During free fall, potential energy decreases while kinetic energy increases, conserving the total mechanical energy.

Front

How do you calculate the kinetic energy of a moving object?

Back

To calculate the kinetic energy of a moving object, use the formula KE = 1/2 mv², substituting the mass and velocity of the object.

Front

What is the unit of measurement for energy in the International System of Units (SI)?

Back

The unit of measurement for energy in the SI system is the Joule (J).
