Forces and Newton's Second Law

What is the formula for force?

• F=M/A
• F=MA
• F=AX
• what is force?

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

What is the formula for force?

• F=M/A
• F=A/M
• F=M*A
• F=M*F

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.
