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

• The 0.78 kg object will have the greatest acceleration.

• The 0.52 kg object will have the greatest acceleration.

• They will both accelerate at the same rate.

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction
