Newton's Second Law Practice

A 20 kg bike accelerates at 10 m/s². Calculate the force on the bike.

• 25 kg

• 20 N

• 200 N

• 10 m/s²

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

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

An object accelerates 5 m/s² when a force of 20 newtons is applied to it. What is the mass of the object?

• 4 kg

• 20 kg

• 0.5 kg

• 2 kg

An object with a mass of 6.0 kg accelerates 4.0 m/s² when an unknown force is applied to it. What is the amount of the force?

• 240 N
• 24 N
• 2.4 N
• 0.24 N

According to Newton's second Law, which would take more force to slow down?

• The silver car

• The green car

• They would both take the same force

Which of these best states Newton's Second Law?

• The greater the mass of an object the greater the force needed to change its motion.

• The greater the mass of an object the less force needed to change its motion.

• The mass of an object does not effect the force needed to change its motion

20 Newtons is an example of a/an:

• mass

• weight

• force

• acceleration

Why would one object have a greater acceleration than another when pushed with the same amount of force?

• The objects have different weights.

• The objects have different forces.

• The objects have different masses.

• The objects are different sizes.

45 m/s² is an example of a/an:

• mass

• weight

• force

• acceleration
