Newton's 2nd Law Practice

The mass of an object is 2 kg and its acceleration is 10 m/s/s. Calculate the force.

• 20 N

• 20 kg

• 5 N

• 5 kg

• 0.2 N

An object has a force of 50 N applied to it and it accelerates at 5 m/s/s. What is the mass of the object?

• 10 kg

• 5 kg

• 2 kg

• 25 kg

• 0.1 kg

If a car of mass 1000 kg accelerates at 2 m/s/s, what is the force exerted by the engine?

• 2000 N

• 500 N

• 2000 kg

• 500 m/s/s

• 2500 N

A force of 30 N is applied to a 3 kg object. What is the acceleration of the object?

• 10 m/s/s

• 90 m/s/s

• 20 m/s/s

• 0.1 m/s/s

A basketball with a mass of 0.60 kg is accelerated with a force of 10.8 N. What is the acceleration of the basketball m/s²?

• 16 m/s²
• 17 m/s²
• 18 m/s²
• 19 m/s²

Newton's 2nd Law

If the block in the picture to the right has an acceleration of 1 m/s² , what would be the block’s mass?

• 8 kg

• 2 kg

• 0.5 kg

• 0.135 kg

If the mass of an object does not change, and you increase the force, what happens to the acceleration?

• acceleration increases

• acceleration decreases

• acceleration stays the same

• acceleration increases and decreases
