• P (capital)

• kilograms (kg)

• d

• meters (m)

• F

• Joules (J)

• m

• Newtons (N)

• W

Match the formula symbol to what it represents

• mass

• P (capital)

• work

• m

• distance

• F

• power

• d

• force

• W

Match the formula symbol to the correct unit

• kg*m/s

• v

• m/s

• p (lowercase)

• s

• t

• m/s²

• a

Match the formula symbol to what it represents

• time

• v

• acceleration

• p (lowercase)

• velocity

• t

• momentum

• a

An object with a positive momentum

• is traveling in the positive direction

• is changing directions

• is traveling in the negative direction

• is not moving

Work is also known as

• energy

• power

• force

• acceleration

If force is equal to mass times acceleration (F = ma), then the units for force can be written as

• kg*m/s

• kg*m/s²

• J/s

• J/kg

If power is equal to energy divided by time (P = E/t), then the units for power can be written as

• kg*m/s

• kg*m/s²

• J/s

• J/kg

The rate at which work is done is known as​ (a)   , which is measured in ​ (b)   Mass in motion is known as ​ (c)   , which is measured in ​ (d)  

• power
• Watts (W).
• momentum
• kg*m/s.

A truck with a velocity of 7 m/s and a bike with a velocity of 7 m/s -

• have the same momentum

• have the same energy

• have a different amount of momentum (the truck has more)

• have a different amount of momentum (the bike has more)
