Physics Fall Review 2020

Front

What is the formula for kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What are the two types of Mechanical Energy?

Back

Kinetic Energy and Potential Energy.

Front

How does the velocity of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to the kinetic energy of an object when its mass is doubled while keeping velocity constant?

Back

The kinetic energy is also doubled.

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 relationship between work and energy?

Back

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

Front

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

Back

The unit of energy is the Joule (J).

Front

What is the effect of friction on mechanical energy?

Back

Friction converts mechanical energy into thermal energy, reducing the total mechanical energy.

Front

What is the significance of the point where kinetic energy is greatest in a system?

Back

At this point, the object has the highest speed and thus the highest kinetic energy.
