Speed, Velocity, and Acceleration

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

Define acceleration in the context of motion.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

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

Back

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

Front

How can you determine if an object is accelerating from a distance vs. time graph?

Back

An object is accelerating if the slope of the distance vs. time graph is changing (increasing or decreasing).

Front

What does it mean if an object has zero acceleration?

Back

Zero acceleration means that the object is either at rest or moving at a constant velocity.

Front

What is the formula for calculating average speed?

Back

Average speed is calculated using the formula: Average Speed = Total Distance / Total Time.

Front

Explain what is meant by 'fast steady speed.'

Back

Fast steady speed refers to a high rate of motion that remains consistent over time, without fluctuations.

What is the significance of the time interval 20-30 seconds in motion analysis?

Back

The time interval 20-30 seconds indicates the period during which the object is moving the fastest, as per the given data.

Front

How can you identify a runner who stopped for a rest in a motion graph?

Back

A runner who stopped for a rest will show a horizontal line on a distance vs. time graph, indicating no change in distance over time.

Front

What does a horizontal line on a distance vs. time graph represent?

Back

A horizontal line represents a state of rest, where the object is not changing its position over time.
