IPC FINAL EXAM

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

What does a position vs. time graph indicate when the line is horizontal?

Back

A horizontal line on a position vs. time graph indicates that the object is not moving.

Front

What is the tallest point of a wave called?

Back

Crest.

Front

What does it mean if velocity is decreasing?

Back

If velocity is decreasing, the object is slowing down.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

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 both speed and direction.

Front

What is a wave's trough?

Back

The trough is the lowest point of a wave.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the change in velocity divided by the time taken for that change.
