Newton’s Law: Law 1 (Law of Inertia) - Definition: An object in motion stays in motion and an object at rest stays at rest - Example:
When a car stops short the groceries on the back seat fly forward and fall.
A ball rolling on the ground speeds up without any force.
A book on a table suddenly starts moving by itself.
A stationary car starts moving without being pushed.
Newton’s 2nd Law - Definition: When a force acts on an object, the object will accelerate proportionally to the force and in the same direction.
When you increase the force you apply on the pedals of the bike, the bike accelerates more.
A stationary object remains at rest unless acted upon by a force.
For every action, there is an equal and opposite reaction.
The mass of an object does not affect its acceleration.
Newton’s Law: Newton’s 3rd Law - Definition: For every action there is an equal but opposite reaction - Example:
The ball hits the bat and the bat hits the ball in the opposite direction with the same force.
A car accelerates because of the friction between the tires and the road.
A book resting on a table remains at rest.
A ball rolling on the ground eventually comes to a stop due to friction.
The Law of Conservation of Energy states that:
Energy can be created and destroyed.
Energy can be created but not destroyed.
Energy cannot be created or destroyed, only transformed.
Energy is always lost in every process.
