## How to excel in Physics and get good grades? Be it any subject, understanding is the crucial factor that determines where you will excel in a subject. When it comes to learning Physics, this is even true. Physics can be as worse as learning a foreign language if you do not understand the basic principles and concepts that lay the foundation. This is why many students struggle to get good marks on the subject.  Some are born to excel in Physics. But for the rest, it requires extra effort to get there.  Here are some tips to help you learn Physics effectively.

Study Physics Constants and basic equation

There are certain commonly used constants in physics which you will see will be recurrently used in various scenarios. Learn them for life just like you learned basic Maths.  Following are the basic constants and equations

Constants

• Speed of light: 3 × 108 meters/second
• Gravity (on earth): 9.81 meters/second2
• Molar gas constant: 8.32 Joules/(mole × Kelvin)
• Avogadro’s number: 6.02 × 1023 per mole
• Planck’s Constant: 6.63 × 10-34 Joules × seconds
• F= ma

Equations

• Acceleration = Change in velocity/change in time
• Force = Mass × acceleration
• Kinetic energy = (1/2)Mass × velocity2
• Current velocity = Initial velocity + (Acceleration × time)
• Work = Displacement × force
• Power = Change in work/Change in time
• Momentum = Mass × velocity
• Velocity = Change in position/Change in time (dx/dt)
