 # How Do You Get An A In Physics?

## What does δ mean in physics?

In general physics, delta-v is a change in velocity.

The Greek uppercase letter Δ (delta) is the standard mathematical symbol to represent change in some quantity.

Depending on the situation, delta-v can be either a spatial vector (Δv) or scalar (Δv)..

## How can I learn physics easily?

## Which science is hardest?

If you sometimes struggle with maths then physics may not come naturally to you and biology may seem much easier. However, the general consensus among students and teachers is that chemistry is the hardest A Level science.

## What are the hardest A levels?

According to SnapRevise, the hardest A-Level subjects to study are:Modern foreign languages.Further maths.History.Physics.English literature.Chemistry.Maths.Psychology.More items…•

## What does P mean in physics?

MomentumMomentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. … This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum.

## What does P stand for in physics electricity?

Electric powerP = IV. Electric power (P) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅V= 1 W.

## Is physics really that difficult?

Physics is hard because it uses mathematics to describe how nature works, and most people hate mathematics, and aren’t willing to do the hard work required to master the tools required to do any useful physics.

## Which is easier physics or chemistry?

On the one hand you can say that chemistry has a lot of memorising, and the physics is more about the principles, but those principles are generally much harder, if you get to a suitable level. So if you are clever but lazy, you’ll do better with physics.

## WHAT IS A in physics?

A. alpha. A = area. A = nucleon number (atomic mass) a = acceleration.
