Newton's Laws of Motion

What is Newton's Second Law of Motion?

• Law of Inertia

• F = MA

• Mass vs Weight

• Acceleration

A 3000 kg plane has an acceleration of 12 m/s^2 on take off. What net force is exerted on the plane?

• 360 N

• 36 N

• 36000N

• 3.6 N

What force can stop a 1400 kg truck accelerating at 7.5 m/s^2?

• 10,500 N

• 10,500

• 10,500 kg

• 10,500 m/s^2

Find the acceleration if the force is 100 N and the mass is 50 kg.

• 200 m/s^2

• 0.2 m/s^2

• 2 m/s^2

• 2.2 m/s^2

How do you find force?

• F = M/A

• F = MA

• F = A/M

• F = M + A

What are the units for acceleration?

• N

• lbs

• m/s^2

• kg

• 8 N

• 9 m/s^2

• 90 kg

• 9 kg

Look at the triangle in your notes. What formula would you use to find mass?

• M = FA

• M= A/F

• M= F - A

• M = F/A

A space worker exerts a net force of 256 N on an object and it accelerates at 8 m/s^2. What is the mass of the object?

• 32 kg

• 3.2 kg

• 320 kg

• .32 kg
