## What physics equations are given in GCSE?

Forces and Motion

• s = d ÷ t. speed = distance ÷ time.
• a = (v-u) ÷ t. acceleration = change in velocity ÷ time.
• F = m x a. Force = mass x acceleration.
• w = m x g. weight = mass x gravity.
• p = m x v. momentum = mass x velocity.
• (mv – mu) = F x t. change in momentum = Force x time.
• d = m � v. density = mass ÷ volume.

## What is the formula for P in physics?

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton’s second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

## How many physics equations are there for GCSE?

Yes, it’s true, there’s a lot of maths in physics. If you take a look at the physics equation sheet on My GCSE Science, you’ll see that for the new 9-1 GCSE there are over twenty equations which you’ll have to remember by the end of Year 11! This blog helps you make sense of it all.

## What are the three equations in physics?

Three Equations of Motion The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²

## How do we calculate efficiency?

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency.

## What does P mean in physics?

Momentum
Momentum 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. The useful thing about momentum is its relationship to force.

## What does T in physics mean?

a = acceleration ∆v = change in velocity ∆t = elapsed time The definition of acceleration.

## What is V and U in physics?

v is the final velocity while u is the initial velocity….

## What are the equations for Physics in Aqa?

AQA GCSE Physics – Equations & Formulae (specification 8463 & 8464) Unit 1: Energy Unit 3: Particle Model of Matter potential difference = current × resistance = total resistance = resistance of component 1 + resistance of component 2 = 1 + 2

## Which is the correct equation for the work energy theorem?

Recall the work-energy theorem, W net = 1 2mv2 − 1 2mv02 W net = 1 2 m v 2 − 1 2 m v 0 2. There is a pressure difference when the channel narrows.

## What are the equations for charge flow and potential difference?

potential difference = current × resistance =𝐼 = resistance of component 1 + = 1+ 2 power = current × potential difference =𝐼 power = (current)2 × resistance =𝐼2 energy transferred = power × time = energy transferred = charge flow × potential difference = AQA GCSE Physics – Equations & Formulae (specification 8463 & 8464)

## What is the purpose of the first unit of Physics?

The goal of this first unit of The Physics Classroom has been to investigate the variety of means by which the motion of objects can be described.
