Speed, Velocity, Acceleration

Front

What is Speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity, meaning it only has magnitude and no direction.

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 of an object. It can be positive (speeding up) or negative (slowing down).

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

If a car travels 60 miles in 1 hour, what is its speed?

Back

Speed = 60 miles / 1 hour = 60 mph.

Front

What happens to the velocity of an object when it accelerates?

Back

The velocity of an object increases if it accelerates in the same direction as its motion.

Front

What is an example of negative acceleration?

Back

A car slowing down as it approaches a stop sign is an example of negative acceleration.

Front

If a runner completes a 100-meter race in 10 seconds, what is their speed?

Back

Speed = 100 meters / 10 seconds = 10 m/s.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.
