Acceleration and Speed Graphs

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

How do you calculate acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration?

Back

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

Front

If a car accelerates from 0 to 70 m/s in 10 seconds, what is its acceleration?

Back

7 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the formula for calculating speed?

Back

Speed = distance / time.

Front

What does a flat line on a speed-time graph represent?

Back

A flat line on a speed-time graph represents constant speed.

Front

What does a steep slope on a speed-time graph indicate?

Back

A steep slope on a speed-time graph indicates a high acceleration.

Front

What does it mean if the speed-time graph is below the time axis?

Back

If the speed-time graph is below the time axis, it indicates that the object is moving in the opposite direction.

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.
