8.6B Speed, Velocity and Acceleration

Front

What is Speed?

Back

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

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down) and is measured in meters per second squared (m/s²).

Front

How do you calculate Speed?

Back

Speed = Distance / Time.

Front

What is the difference between Speed and Velocity?

Back

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

Front

What does it mean to turn left in terms of motion?

Back

Turning left indicates a change in direction, which is an example of acceleration.

Front

What is an example of Speed?

Back

Traveling at a constant speed of 60 mph on a highway.

Front

What is an example of Velocity?

Back

Traveling 50 mph east on a straight road.

Front

What is an example of Acceleration?

Back

A car increasing its speed from 30 mph to 60 mph in 5 seconds.

Front

What unit is used to measure Acceleration?

Back

Meters per second squared (m/s²).
