Find the force required to move a box having mass 10 kg with an acceleration of 9m/s² .

• 10N

• 90N

• 100N

• 20N

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?  (F=ma)

• The one with a mass of .78 kg will have the greatest acceleration.
• The one with a mass of .52 kg will have the greatest acceleration.
• They will both accelerate at the same rate.

As force applied to a textbook increases, what happens to its acceleration?

• Stays the same

• Decreases

• Increases

• 5N

• 3.825Kg

Newton's second law of motion describes acceleration as force divided by __________.

• mass
• inertia
• speed
• direction

• The ball will go faster.
• The ball will slow down.
• The ball will stop. 
• The ball will fly in the air.
