Newton's Second Law

A 20 kg bike accelerates at 10 m/s². How much force was applied?

• 25 Newtons

• 20 Newtons

• 200 Newtons

• 10 Newtons

What Unit do we Measure Force in? 

• Newtons
• Joules
• Force
• Don't know

F=MA
An object of mass 10 kg is accelerated upward at 2 m/s².  What force is required? 

• 20 N
• 2 N
• 5 N
• 0 N

20 N is the

• mass
• weight
• force
• acceleration 

45 m/s² is the... 

• Mass
• Force 
• Acceleration
• weight

Will it take more force to push an empty shopping cart or a shopping cart that is full?

• The empty shopping cart
• The full shopping cart
• They will take the same amount of force

How much force is needed to accelerate a 2 kg physics book to an acceleration of 6 m/s/s?

• 36 N
• 12 N
• 3 N
• 0.33 N

When force is 20 N, mass is 5 kg, what is acceleration?

F = ma

• 25 m/s²

• 5 m/s²

• 100 m/s²

• 4 m/s²

Newton's Second Law can be expressed as

• v = d / t

• E = mc²

• F = ma

• m₁v₁ = m₂v₂

Jenny applies a 60 N force to a 20 Kg cart, what is the acceleration of the cart if friction can be neglected?

• 1200 m/s²

• 0.33 m/s²

• 20 m/s²

• 3 m/s²
