Unit 3 - TEKS 7.7A-D

Front

What does Newton's First Law state about the motion of an object when no external force acts on it?

Back

An object in motion will remain in motion at a constant speed in a straight line unless acted upon by an external force.

Front

Define velocity in terms of speed and direction.

Back

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

Front

What does a distance-time graph represent in terms of an object's motion?

Back

A distance-time graph shows how the distance traveled by an object changes over time.

Front

What does a steep slope on a distance-time graph indicate about an object's speed?

Back

A steep slope indicates that the object is moving at a fast speed.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If an object returns to its starting position, what can be inferred about its distance-time graph?

Back

The graph will show a return to the starting point, indicating that the distance traveled is zero at the end of the time interval.

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 the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is at rest and not changing its position over time.

Front

What is the significance of the area under a speed-time graph?

Back

The area under a speed-time graph represents the total distance traveled by the object.
