Speed, Velocity, and Acceleration

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

Front

When does acceleration occur?

Back

Acceleration occurs when an object speeds up, slows down, or changes direction.

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 speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or centimeters per minute (cm/min).

What is velocity?

Back

Velocity is the rate at which an object changes its position in a specific direction.

Front

What is an example of positive acceleration?

Back

A car speeding up from 20 m/s to 50 m/s is an example of positive acceleration.

What is an example of negative acceleration (deceleration)?

Back

A car slowing down from 60 m/s to 30 m/s is an example of negative acceleration.

Front

What does it mean to change direction?

Back

Changing direction means altering the path of an object, which can also result in acceleration even if the speed remains constant.

Front

How can acceleration be calculated?

Back

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

Front

What is uniform acceleration?

Back

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