Newton's 2nd Law

If the man pushes with an equal amount of force, which object will accelerate more?

• Car because it has more mass

• Lawnmower because it has less mass

• Car because it has less mass

• Lawnmower because it has more mass

What is Newton's 2nd Law?

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• F = ma

• Friction

A force of 90N is applied to each cart below, which one will accelerate the fastest?

• Cart 1
• Cart 2
• Cart 3 
• Cart 4

When mass is 10 kg, acceleration is 2 m/s/s, what is force?
F = ma

• 5 N
• 20 N
• 8 N
• 12 N

The force of a cart doubles.  What happens to the cart's acceleration?

• It doubles
• It quadruples 
• It halves
• It quarters

A force of 250 N is applied to an object that accelerates at a rate of 5 m/sec².  What is the mass of the object?

• 100kg 
• 1,250kg
• 50kg
• 5kg

If a force of 50 Newton's was applied to an object with a mass of 500 grams, what will the object's acceleration be?

• 10 m/s^2
• .1 m/s^2
• 100 m/s^2
• 1 m/s^2

True or False. Acceleration of an object is directly proportional to the net force acting on it

• True

• False

Your 2500 kg car experiences a net force of 5000 N. How fast will it accelerate?

• 20 m/s²

• 0.5 m/s²

• 2 m/s²

• 120 N

What is the net force for this situation?

• 17 N Right
• 17 N Left
• 3 N Right
• 3 N Left
