Speed, Velocity, Acceleration

Front

What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How does velocity differ from speed?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

How do you calculate acceleration?

Back

Acceleration = (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

What does it mean if an object is accelerating?

Back

An object is accelerating if it is changing its velocity, which can mean speeding up, slowing down, or changing direction.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
