Speed, Velocity & Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in units like 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, combining both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or slowing down.

Front

What is the formula for calculating 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 if an object has a constant speed?

Back

It means the object is moving the same distance in equal intervals of time without speeding up or slowing down.

Front

What is a negative acceleration?

Back

Negative acceleration, or deceleration, occurs when an object slows down, indicating a decrease in speed.

Front

How can you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is an example of velocity?

Back

A car traveling 60 mph East is an example of velocity because it includes both speed and direction.

Front

What is an example of acceleration?

Back

A roller coaster speeding up from 10 mph to 50 mph in 5 seconds is an example of acceleration.
