Speed, Velocity, Acceleration Flashcard

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 55 miles per hour south.

Front

What is acceleration?

Back

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

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object's speed increases over time.

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object's speed decreases over time.

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 a runner's speed increases from 9 mph to 9.8 mph, what type of acceleration is this?

Back

This is an example of positive acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What unit is commonly used to measure speed?

Back

Common units for measuring speed include miles per hour (mph) and meters per second (m/s).

Front

What does it mean if an object has a constant speed?

Back

If an object has a constant speed, it means it is traveling the same distance in equal intervals of time.
