Physics Mid-term Exam 2024

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude.

Front

What distinguishes speed from velocity?

Back

Velocity includes direction, while speed does not.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the unit of acceleration in the SI system?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity representing the total path length, while displacement is a vector quantity representing the shortest path from the initial to the final position.

Front

What is the formula for calculating velocity?

Back

Velocity = Displacement / Time.

Front

What is the significance of direction in physics?

Back

Direction is crucial in vector quantities, as it determines the vector's orientation in space.
