What is speed?

Back

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

Front

What does a horizontal line on a speed graph indicate?

Back

A horizontal line indicates that the object is moving at a constant speed; it is neither accelerating nor decelerating.

Front

What does a steep slope on a speed graph represent?

Back

A steep slope indicates a high speed; the steeper the slope, the faster the object is moving.

Front

What does a downward slope on a speed graph indicate?

Back

A downward slope indicates that the object is decelerating or slowing down.

Front

What is acceleration?

Back

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

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken: Speed = Distance / Time.

Front

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

Back

Time can be found using the formula: Time = Distance / Speed.

Front

If a car travels 100 km at a speed of 50 km/h, how long does it take?

Back

It takes 2 hours (Time = 100 km / 50 km/h).

Front

What does a speed graph with a flat line at zero indicate?

Back

A flat line at zero indicates that the object is not moving.

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.
