Forces Quiz

When solving for average velocity which tool will help best :

• number line

• plotted numbers

• number values

• speed numbers

Velocity is different from speed because it includes:

• a short distance

• North

• South

• direction

Average acceleration units are:

• m/s squared

• m/s

• distance/time

• really fast

Why does simplifying 49N/5kg into 9.8N/kg work? Select the best answer

• why deal with 5kg when you can deal with one

• because decimals are better

• the calculated fraction can be multiplied by any given amount of kg

• it just is

EXAMPLE: A dog weighs 75kg. When solving for how many Newtons it takes to life the dog, what ratio is needed?

• 45g/5N

• 49N/5kg

• 9.8N

• 4/1

A ball is traveling from 0m West to - 12 m West in 6 seconds. What unit does the final answer HAVE to have?

• number value with direction

• negative number value with direction

• only direction

• average time

A ball is traveling from 0m West to 12 m West in 6 seconds. What is the average velocity for the ball?

• 2 m/s

• 2 m/s East

• 2 m/s West

• 2 sec

What is the average acceleration equation state?

• end velocity - start velocity/time

• end position - start position/time

• start velocity + end velocity/time

• end velocity - start velocity/distance

What is the ratio 45N/5kg equal to?

• 9.8N/5kg

• 98N/5kg

• 98N/kg

• 9.8 N/kg
