World of Science

• Science is a very broad and in-depth subject with lots of different branches like Newton's laws, gravity, physical and chemical changes and so on.

Newton's 1st law

• Newton's first law is the same as inertia. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Newton's 2nd law

• Newton's 2nd law is the most powerful law of the three. The relationship between an object's mass, its acceleration and the applied force is F = ma. Acceleration and force are vectors in this law the direction of the force vector is the same as the direction of the acceleration vector.

Newton’s 3rd law

• Newtons 3rd law is probably the best known law of all. For every action there is an equal and opposite reaction.

Gravity

• A force that is pull produced by the mass of the earth.

Acceleration

• Acceleration is an increase in velocity.

Resistance

• Resistance is an opposing force.

Force• Force is a push or pull

Potential Energy

• Potential Energy (PE) is energy stored inside of a body or a system.

Kinetic Energy

• Kinetic Energy (KE) is energy of body caused by motion.

Chemical and Physical Changes

• Chemical changes are when 2 or more items are combined a new substance is formed.

• Physical changes are when 2 or more items are combined no new substance is formed.

Homogenous and heterogeneous mixtures

• Homogenous mixtures are mixtures where you cant see the different particles.

• Heterogeneous mixtures are when you can see the different particles.

Elements, compounds, and atoms

• Elements are pure chemical substance consisting of one type of atom.

• Compounds are chemical substances consisting of 2 or more types of elements.

• Atoms are the basic unit of matter.
