Science Chapter Two Test Review

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If a car travels 20 miles in 1 hour and 30 miles in 1 hour, what is the average speed for the entire trip?

Back

Average speed = (20 miles + 30 miles) / (1 hour + 1 hour) = 25 miles per hour.

Front

What happens to the average speed if the time taken increases while the distance remains the same?

Back

The average speed decreases.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

What does it mean when an object is accelerating?

Back

An object is accelerating if it is changing its speed or direction.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

What is the relationship between speed and time in motion?

Back

Speed is directly proportional to distance and inversely proportional to time.
