What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

How is acceleration calculated?

Back

Acceleration (a) is calculated using the formula: 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

What does a position vs. time graph show?

Back

A position vs. time graph shows how the position of an object changes over time.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line indicates that the object is at rest (not moving).

Front

What does a steep slope on a position vs. time graph indicate?

Back

A steep slope indicates that the object is moving at a high speed.

Front

What does a curved line on a position vs. time graph indicate?

Back

A curved line indicates that the object is accelerating.

Front

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

Back

The acceleration is 7 m/s².

Front

What does constant velocity mean?

Back

Constant velocity means that an object is moving at a steady speed in a straight line.
