Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

How do you convert kilometers to meters?

Back

1 kilometer = 1000 meters.

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 distance-time graph represent?

Back

A distance-time graph shows how distance changes over time, indicating the speed of an object.

Front

If a runner runs at a speed of 4.5 m/sec for 18 minutes, how far do they run?

Back

4.86 km.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

How do you calculate average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the formula for calculating velocity?

Back

Front

What is the significance of the slope in a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object.
