momentum basics

Momentum is a 

• Scalar
• Vector
• Mentum is an awesome candy bar I want mo of

The formula for momentum is

• p=mv²
• p=m²v
• p=mv
• m=pv

A 3kg car is traveling at 14 m/s to the right, what is the cars momentum?

• 4.67 kg*m/s
• 42 kg*m/s
• - 42 kg*m/s
• .21 kg*m/s

A 14 kg donkey is walking briskly at 22 m/s to the left. What is her momentum?

• 308 kg*m/s
• -308 kg*m/s
• 1.57 kg*m/s
• -6776 kg*m² / s²

Net momentum can be negative

• True
• False
• Potato

In math, what does "the product" mean?

• The sum of two numbers

• The difference between two numbers

• The result of dividing one number by another

• The result of multiplying two numbers

Convert 2500 grams to kilograms.

• 2.5 kg

• 25 kg

• 0.25 kg

• 250 kg

What is momentum defined as in physics?

• The product of the mass and acceleration

• The product of the mass and velocity

• The rate of change of velocity

• The force applied on an object

How is change in momentum calculated?

• Initial momentum plus final momentum

• Final momentum divided by initial momentum

• Final momentum minus initial momentum

• Initial momentum times final momentum

What are the units of momentum?

• m/s

• kg

• N (Newtons)

• kg·m/s
