What is acceleration?

Back

Acceleration is the rate at which velocity changes over time.

Front

What does it mean if an object is accelerating?

Back

It means that the object's velocity is changing, which can be due to a change in speed or 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.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as speed.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity.

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, also known as deceleration, indicates that an object is slowing down.

Front

How can you tell if an object is accelerating from a velocity graph?

Back

If the slope of the velocity graph is increasing, the object is accelerating; if the slope is decreasing, the object is decelerating.

Front

What is uniform acceleration?

Back

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

Front

What is the formula for acceleration?

Back

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