Constant Speed Practice

Front

What is constant speed?

Back

Constant speed refers to the condition where an object covers equal distances in equal intervals of time, regardless of the length of the time intervals.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the basic unit for speed in the International System of Units (SI)?

Back

The basic unit for speed is meters per second (m/s).

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time, with speed on the vertical axis and time on the horizontal axis.

Front

What does a horizontal line on a speed-time graph indicate?

Back

A horizontal line indicates that the object is moving at a constant speed.

Front

How do you determine the distance traveled from a speed-time graph?

Back

The distance traveled can be found by calculating the area under the speed-time graph.

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 includes both speed and direction.

Front

What is a head start in a race?

Back

A head start is when one runner begins the race at a point ahead of the starting line, giving them an advantage over the other runners.

Front

How can you determine when one runner passes another?

Back

A runner passes another when they reach the same position at the same time, which can be determined by comparing their distance-time equations.

Front

What does it mean if a runner is standing still?

Back

If a runner is standing still, their position does not change over time, meaning their speed is 0 m/s.
