Conceptual Physics Final Exam Review

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that describes how fast an object is moving, while velocity is a vector quantity that includes both the speed and the direction of the object's motion.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula: p = mass (m) × velocity (v).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity and force.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as speed and mass.

Front

What happens to the momentum of an object if its velocity doubles?

Back

If the velocity of an object doubles, its momentum also doubles, assuming mass remains constant.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does mass affect acceleration in a collision?

Back

In a collision, a larger mass will experience a smaller acceleration compared to a smaller mass when the same force is applied.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

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

Back

According to Newton's Second Law, force (F) is equal to mass (m) times acceleration (a): F = m × a.
