Speed Velocity and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in units like meters per second (m/s) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, for example, 60 km/h north.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can involve speeding up, slowing down, or changing direction.

Front

What is deceleration?

Back

Deceleration is a type of acceleration that occurs when an object slows down.

Front

What does it mean when an object is at rest?

Back

An object is at rest when it is not moving and its speed is zero.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is a speed graph?

Back

A speed graph shows how speed changes over time, typically with time on the x-axis and speed on the y-axis.

Front

What is an acceleration graph?

Back

An acceleration graph shows how acceleration changes over time, with time on the x-axis and acceleration on the y-axis.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same speed throughout its motion.

Front

What is an example of positive acceleration?

Back

A car speeding up from 20 m/s to 40 m/s is an example of positive acceleration.
