Average Speed Practice

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is usually expressed in miles per hour (mph) or meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If a car travels 250 miles in 4 hours, what is its average speed?

Back

62.5 mph.

Front

What does it mean if an object is at rest?

Back

An object is at rest when it is not moving and its speed is 0.

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

If Soccer Ball A travels 15 feet in 3 seconds and Soccer Ball B travels 12 feet in 2 seconds, which ball is faster?

Back

Soccer Ball B is faster.

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time.

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

If a driver is at rest for 1 hour, how does it affect their average speed?

Back

The average speed will decrease because the total time includes the time spent at rest.

Front

What is the significance of a speed graph?

Back

A speed graph visually represents how speed changes over time, showing periods of acceleration, constant speed, and rest.
