Speed vs Velocity

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 refers to the speed of an object in a specific direction.

Front

Define speed in terms of distance and time.

Back

Speed is defined as the distance traveled divided by the time taken to travel that distance. The formula is Speed = distance/time.

Front

What is the unit of measurement for speed?

Back

The unit of measurement for speed is typically meters per second (m/s) or miles per hour (mph).

Front

What is the unit of measurement for velocity?

Back

The unit of measurement for velocity is also typically meters per second (m/s) or miles per hour (mph), but it includes a direction.

Front

If a car travels 150 miles in 3 hours, what is its speed?

Back

Speed = distance/time = 150 miles / 3 hours = 50 mph.

Front

What does it mean when we say an object has a constant speed?

Back

An object has a constant speed when it covers equal distances in equal intervals of time, regardless of the direction.

Front

What is the formula for calculating velocity?

Back

Velocity = displacement/time, where displacement is the change in position of an object.

Front

How does acceleration relate to speed and velocity?

Back

Acceleration is the rate of change of velocity over time. It can occur with a change in speed, direction, or both.

Front

What is an example of velocity?

Back

An example of velocity is a car traveling 60 mph north.

Front

What is an example of speed?

Back

An example of speed is a runner completing a 5-mile race in 40 minutes, which is 7.5 mph.
