Forces in Matter

Forces can act from a distance o through contact. When they act from a distance they are called non-contact forces. When they come into contact with the object they are called contact forces.

NON-CONTACT FORCES

Magnetism is a force that can attract or repel mangetic objetcs. Let's watch the following video.

Gravity is a non-contact force that pulls objects towards  each other.

📌 There are two different contact forces: Applied force and Buoyant force.

📌When an object is put in a liquid there is an upward force acting on it called buoyancy. This is what makes objects float.

Changes in Matter

Matter can change in many ways. These changes are classified into two types: Physical changes and Chemical changes.

PHYSICAL CHANGES

In a physical change no new substance is formed and properties of the substance stay the same.

CHEMICAL CHANGES

In a chemical change a new substance or substances form.
