Physics Exam Review

Front

What is the SI unit for wavelength?

Back

The SI unit for wavelength is meters (m).

Front

What is the SI unit for acceleration?

Back

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

Front

Calculate the speed of an object that travels 30 meters in 5 seconds.

Back

The speed is 6 m/s.

Front

What is the net force acting on a 10 kg object that accelerates at 3 m/s²?

Back

The net force is 30 N.

Front

What does the velocity-time graph of an accelerating object look like?

Back

It looks like a straight diagonal line.

Front

Define speed in physics.

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of force in the SI system?

Back

The unit of force is the Newton (N).

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is at rest.
