Speed, Velocity, & Acceleration FLASHCARD

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total 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 acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object is slowing down.

Front

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

Back

A horizontal line on a speed vs. time graph indicates that the object is moving at a constant speed.

Front

What does a line with a positive slope on a speed vs. time graph indicate?

Back

A line with a positive slope indicates that the object is accelerating.

Front

What does a line with a negative slope on a speed vs. time graph indicate?

Back

A line with a negative slope indicates that the object is decelerating.

Front

What is an example of constant speed?

Back

An example of constant speed is a car traveling at 60 km/h on a straight road without changing speed.

Front

What is an example of acceleration?

Back

An example of acceleration is a car moving at a constant speed around a circular track, as its direction is changing.
