Newtons three laws

.....................................................................................................................................................................................................

Everyone knows that heavier objects require more force to move the same distance as lighter objects. For an example <-- see this picture for him it is easy to kick a scoccer ball because its light but if he trys to kick a brick wall because its heaiver(way heavier) its hard to kick and will hurt his foot. The Second Law gives us a relationship between force, mass, and acceleration. It can be expressed as a mathematical equation:F = M Aor Force = Mass times Acceleration.

This law is often called "the law of inertia".<----This picture shows the skater zooming along untll he hits the unblanaced force which is the rock and of course falls over and smashes into a million pieces(that wont happen to you you'll just hurt yourself!).

Activity

This means that for every force there is a reaction force that is equal in size, but opposite in direction. For example see this rocket --> the acton s the thruster turns on and the reaction is the rocket moving in the oppisite direction.

For every action there is an equal and opposite re-action.

Newtons Three Laws

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).

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.

Here is a fun activity you can do at home!
