they communicate their finding by a scientific  journal to their colleagues.

They also give presentations to their colleagues and the public.

They communicate their ideas to get opinions from other scientists.

To get a real image you have to use converging lens, but to get a virtual image you have to use a diverging lens. By: Ethan

It transfers through neighboring molecules that are contact with one another. Conduction, Radiation, and Convection.

Mirrors are lighter, and they are easier than lenses to make perfectly smooth. The mirrors are in a telescope and are called optics. Reflecting telescopes use mirrors instead of lenses because the mirrors collect light. Mirrors only have one reflective surface.

first law: When you are in a car suddenly stops you would still by in motion if you do not have a seatbelt on.
second law: when you are pushing a shopping cart around Walmart.
third law: When you are playing tug of war with your friends.

Thermal energy transfers occur in three ways: through conduction, convection , and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.

Newton's first law can be explained through travelling on a bus. When the bus driver  quickly breaks people tend to feel a pull in the forward direction. The reason behind this feeling by the passengers sitting inside the bus is the law of inertia. The inertia of motion on our body continues to maintain a state of motion even after the bus stops from pushing people in the forward direction.

First Law - if an object is pushed across ice with no force of friction acting against it, it will continue at the same speed until another force acts against it.

Second Law - if an object with a mass of 2 kilograms is pushed with an acceleration of 6 m/s^2, it will have a force of 12 N.

Third Law - if you push a box with a force of 15 N, the box will react with an equal force toward you.

Newtons First Law : Objects in motion stay in motion and objects at rest stay at rest unless acted upon by a force. If you throw a object in space it will go forever unless it is stopped by a force.
Newtons Second Law : F=ma, the more acceleration a ball has the more force will be exerted on impact.
Newtons Third Law : For every action there is a equal and opposite reaction, for example if you punch a wall the force you exerted on the wall will be exerted back which is why your hand hurts after.

1:When a car is in motion, it stays in motion unless acted upon by outside forces like friction, brakes, or a wall
2:force(foot in child's face) = mass(weight of leg) x acceleration(leg moves)
3: action: car hits wall, reaction: wall crumples the front of the car

Conduction : Conduction is the transfer of heat when two objects touch.
Convection : Convection is when colder areas liquid or air take place of the warmer areas because of the rising of the air.
Radiation : Radiation can transfer heat without any medium to travel or mass to be exchanged. Heat from the sun is radiation as an example.

Force is equal to mass times acceleration and is measured in newtons.
Work is equal to force times distance and is measured in joules.
Energy is the ability to do work and is measured in joules.
Power is equal to the amount of work done per second and is measured in watts.

The real image is formed by rays converge.

A virtual image occurs when rays appears to diverge.

They lie in different ways when the are produced.

You can write reports or write in journals. Also presentations in class or colleagues.

It is a rotation by power. The device has electric power.

force (n) =mass x accelaration
work (j) =force x displacement
power (w) =work/time
kinetic energy (kg m^2 s^2)= 1/2 mass x velocity
