Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed (S) = Distance (d) / Time (t).

Front

What does a constant speed indicate on a speed vs. time graph?

Back

A constant speed indicates that the object is moving at the same rate over time, represented by a horizontal line on the graph.

Front

What does negative acceleration mean?

Back

Negative acceleration means that the object is slowing down.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur due to changes in speed or direction.

Front

Why does a car accelerate when going around a corner?

Back

A car accelerates when going around a corner because it is changing direction, even if its speed remains constant.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t).

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 speed vs. time graph?

Back

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

Front

What does an increasing slope on a speed vs. time graph indicate?

Back

An increasing slope indicates that the object is accelerating.
