Chapter 5 - Newton's Second Law - Review!

Why does it hurt more to get stepped on by a high heel vs a sneaker?

• There is more area for the force to spread out

• There is less area for the force to spread out

• The amount of area is the same

The amount of force per unit area is called...

• Pressure

• Acceleration

• Speed

What is the formula for pressure?

• F = m*a

• P = F/A

• V = d/t

What is the SI Unit for pressure?

• Newtons

• meters/second

• Pascals

Which would exert more pressure: a ballerina balancing on one foot, or a snowboarder balancing on two feet?

• Ballerina

• Snowboarder

• Both exert the same amount of pressure

According to Newton, what two quantities contribute to acceleration?

• Mass and Distance

• Speed and Force

• Mass and Force

Which would accelerate more when pushed with the same force: an empty shopping cart or a full shopping cart?

• Empty shopping cart

• Fully shopping cart

• Both will accelerate at the same rate

Which best describes the relationship between net force and acceleration?

• Directly proportional (one increases, the other increases)

• Inversely proportional (one increases, the other decreases)

• No relation (one increases, the other stays the same)
