Unit 8.1 Flashcard 2

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How can you determine if two objects have the same average speed?

Back

Two objects have the same average speed if they cover the same distance in the same amount of time.

Front

What does it mean for an object to move at a constant speed?

Back

An object moves at a constant speed when it covers equal distances in equal intervals of time.

Front

What is the significance of equally spaced dots in a motion diagram?

Back

Equally spaced dots indicate that the object is moving at a constant speed.

Front

How can you tell if two objects have the same speed at a specific time?

Back

Two objects have the same speed at a specific time if their positions are the same at that 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 does a graph showing constant speed look like?

Back

A graph showing constant speed is represented by a straight line with a constant slope.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What does it mean if the slope of a distance-time graph is zero?

Back

A zero slope on a distance-time graph indicates that the object is at rest.

Front

How can you identify acceleration in a motion graph?

Back

Acceleration can be identified in a motion graph by a changing slope; a steeper slope indicates greater acceleration.
