Science Week 7

Motion of the sun

• The sun moves around a great galactic core

• That moves around the universe

The Moon

The moon revolves around Earth

The moon has many scars from the millions of rocks that have hit it.

Isaac Newton

• Well known for his discoveries in optics (white light composition) and mathematics (calculus), it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous. His formulation of the laws of motion resulted in the law of universal gravitation.

Law No 1

Everything either stays at rest or keeps moving at the same rate in a straight line unless it is acted upon by another force

Law No 2

When a force hits an object, the object will move in the direction of the force. The change in motion, or acceleration of the object, depends on the power of the force.

Law No 3

To every action, there is an equal and opposite Reaction
