Physics Semester 1 Review

Front

What is Newton's second law of motion?

Back

The relationship between force (F), mass (m), and acceleration (a) is given by the formula F = m × a.

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction, such as velocity or force.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction, such as speed or mass.

Front

What is force?

Back

A push or pull on an object.

Front

What does inertia mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

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 first law of motion?

Back

An object in motion tends to stay in motion and an object at rest tends to stay at rest until acted on by an unbalanced force.

Front

What is the unit of force in the SI system?

Back

The unit of force is the Newton (N).

Front

How do you calculate the average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

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 direction.
