H Constant Velocity Test 2024

Front

On a distance vs. time graph, the steeper the slope _____

Back

the faster the speed.

Front

Vector quantities need both a magnitude and a _____

Back

direction.

Front

What is the velocity shown in this xt graph for the negative slope?

Back

-2 m/s.

Front

What is the best variable or number to replace the variable Y with in the equation Y = mx + b if we want to represent the line shown?

Back

position.

Front

How long would it take for the object to reach a final position of -20 m from its starting position/time?

Back

20 s.

Front

Define constant velocity.

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.

Front

What does a horizontal line on a distance vs. time graph represent?

Back

An object at rest.

Front

Explain 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 acceleration?

Back

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

Front

What does a negative slope on a distance vs. time graph indicate?

Back

The object is moving back towards the starting point.
