Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or slowing down.

Front

What does a constant speed graph look like?

Back

A constant speed graph is represented by a straight line with a positive slope on a distance-time graph.

Front

What does a decreasing speed indicate on a graph?

Back

A decreasing speed indicates that the slope of the distance-time graph is becoming less steep, showing that the object is slowing down.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What does it mean if two objects have the same average speed?

Back

It means both objects covered the same distance in the same amount of time, regardless of their individual speeds at different moments.

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 does a steeper graph indicate in terms of speed?

Back

A steeper graph indicates a higher speed, as the distance covered increases more rapidly over time.

Front

What is a velocity-time graph?

Back

A velocity-time graph shows how an object's velocity changes over time, with time on the x-axis and velocity on the y-axis.

Front

What does a horizontal line on a velocity-time graph represent?

Back

A horizontal line on a velocity-time graph represents constant velocity, meaning the object is moving at a steady speed.
