Newton’s laws

1. Newton’s laws By: Brittany keels 8th period

2. First law • An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. • This means to me that the first law is objects doing what they are doing.

3. Second law • Acceleration is produced when a force acts upon a mass. The greater the mass(of the object being accelerated)the greater the amount of force needed(to accelerate the object). • This means more mass means more force needed to accelerate.

4. Third law • For every force , there is an equal and opposite force. • When you push an object,it pushes back. The rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force.

6. Score • Brittany, • This is extremely well done! Your animations and explanations are excellent. Your citation will work for this assignment, but in the future, I’d prefer that you are more specific (such as links to the actual pages you used.) • 10.5/12
