IPC Physics Semester Test

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

Calculate the speed of an object that travels 60 meters in 4 seconds.

Back

15 m/s

Front

What is the definition of force?

Back

A push or a pull that acts on an object.

Front

What device uses a free-moving magnetic needle to show direction?

Back

Compass.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 a free body diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does it mean if the net force on an object is zero?

Back

The object is in equilibrium and there is no change in its motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
