Physics Final Exam

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it. This means that the momentum before an event (like a collision) is equal to the momentum after the event.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. For example, an object at a height has gravitational potential energy.

Front

Where is maximum potential energy located on a roller coaster?

Back

Maximum potential energy is located at the top of a big hill on a roller coaster.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate net force when multiple forces are acting in opposite directions?

Back

To calculate net force, subtract the smaller force from the larger force and apply the direction of the larger force.

Front

What is the correct unit for measuring velocity in physics?

Back

The correct unit for measuring velocity in physics is meters per second (m/s).

Front

What is the formula for calculating momentum?

Back

Front

What happens to kinetic energy when an object comes to a stop?

Back

When an object comes to a stop, its kinetic energy is converted to other forms of energy, such as heat due to friction.

Front

What is the relationship between force, mass, and acceleration?

Back

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
