Laws of Motion

Newton's first law of motion: 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.

My own words: A moving object will continue moving unless an unbalanced force is applied to it.

Example of demonstration: I could kick a ball to a wall and show how the wall stops the ball because it an unbalanced force.

explanation of the picture: This shows that the dirt bike is stopped because and unbalanced force was applied to the dirt bike.

Newton's second law of motion: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Own words: The second law of motion basically means that the heavier an object is, then the more force that is needed to be applied.

Explanation of demonstration: I could have another person stand up there with me and we could push against each other to show how you have to apply more force for the more mass there is.

Explanation of the picture: The picture shows that a lot of force has to be applied because they are trying to pull the rope all the way over to their side, so therefore they are having to apply more force.

Newton's third law of motion: For every action there is an equal and opposite re-action.

Own Words: In my own words this means that there is always a reaction it is just going in the opposite direction.

Explanation of demonstration: I could push somebody or somebody could push me and then there would be a reaction and and opposite reaction.

Explanation of the picture: This picture represents how there is somebody tackling another person but there is an opposite reaction.
