Acceleration

Front

What is acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

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 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 quickly.

Front

What does a negative acceleration mean?

Back

Negative acceleration means the object is slowing down.

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

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the significance of the area under a velocity vs. time graph?

Back

The area under a velocity vs. time graph represents the displacement of the object.
