8.6B Speed, Velocity, & Acceleration Practice

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

How do you calculate acceleration?

Back

Acceleration = (final velocity - initial velocity) / time

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

If a runner travels 100 m South in 10 seconds, what is their velocity?

Back

10 m/s South

Front

What is the unit of acceleration?

Back

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

Front

A drag racer accelerates from 0 m/s to 200 m/s in 5 seconds. What is the acceleration?

Back

40 m/s²

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down (deceleration).

Front

What is the initial velocity of an object that starts from rest?

Back

The initial velocity is 0 m/s.

Front

How do you find the final velocity of an object given its initial velocity and acceleration?

Back

Final velocity = initial velocity + (acceleration × time)

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity as it indicates the path of motion, making it a vector quantity.
