Acceleration

Front

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

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

If an object is at rest, what is its acceleration?

Back

If an object is at rest, its acceleration is 0 m/s².

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.

Front

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

Back

A flat line on a position vs. time graph represents no motion (the object is at rest).

Front

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

Back

A steep slope on a position vs. time graph indicates a high speed.

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.
