Physics Question

You should learn this important note Physics Important Notes (High School)

1. Motion

Motion = Change in position with time

Distance = Total path covered

Displacement = Shortest distance in a specific direction

Speed = Distance Time

Velocity = Displacement Time

Acceleration = Change in velocity Time

Formula:

2. Force and Laws of Motion

Force = Push or pull

SI unit = Newton (N)

Newtons Laws:

An object remains at rest or in uniform motion unless acted upon by a force

Force = Mass Acceleration

Every action has an equal and opposite reaction

3. Work, Energy and Power

Work = Force Distance

Energy = Capacity to do work

Types: Kinetic energy and Potential energy

Power = Work Time

Formula:

4. Gravitation

Every object in the universe attracts every other object

Formula:

5. Light

Light travels in a straight line

Reflection = Bouncing back of light

Refraction = Bending of light

Law of Reflection:

Angle of incidence = Angle of reflection

6. Electricity

Electric current = Flow of electric charge

SI unit = Ampere (A)

Ohms Law:

7. Magnetism

Magnets have two poles: North and South

Like poles repel, unlike poles attract

8. Sound

Sound travels in the form of waves

It requires a medium (cannot travel in vacuum)

Exam Tips:

Learn formulas and units

Practice numerical problems daily

Draw neat diagrams

Write answers in points
