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.

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

Unit of mass

• m/s 2
• m/s
• newtons
• kg

The mass of a car is 1000 kg. How much force would be required to accelerate the car at a rate of 3 m/s²?

• 1000 ÷ 3

• 3 ÷ 1000

• 1000 x 3

The mass of a car is 1000 kg. How much force would be required to accelerate the car at a rate of 3 m/s²? The answer to this question is most likely (HINT: Look at the units!!!) -

• 3000 N

• 3000 m/s²

• 3000 kg
