## Should I change topics in GCSE physics?

Generally the science EEs get graded really low, so if you care about your grade switch to English or History. If you don’t care about the grade, and want to stick with physics you ought to change your topic.

## What are the kinematic equations of motion?

The kinematic equations are simplifications of object motion. Three of the equations assume constant acceleration (equations 1, 2, and 4), and the other equation assumes zero acceleration and constant velocity (equation 3).

## What is the first equation of motion in physics?

First Equation of Motion. First equation of motion relates velocity, time and acceleration. Now in ∆uxy, tanθ =. tanθ =. We also know that tanθ is nothing but the slope and slope of v – t graph represents acceleration. ⇒ v = u + at ———– (1) This is the first equation of motion where, v = final velocity.

## How do you change the acceleration in a kinematic equation?

Kinematic equations are derived with the assumption that acceleration is constant. When the acceleration is constant, average and instantaneous acceleration are the same. So, we can replace a ¯ with a. In the notations, we do some changes, first, we take the initial time as 0, and the final time as t, so we have the time interval, Δ t = t.

## What are the components of the equation of motion?

To state this formally, in general an equation of motion M is a function of the position r of the object, its velocity (the first time derivative of r, v = drdt), and its acceleration (the second derivative of r, a = d 2rdt 2), and time t.

## What is the formula for Conservation of energy in physics?

mM mmMV V m + =+ ⇒= conservation of energy to give, ( ) ( ) , where V is the velocity12 2 acquired by the block+bullet in the upward direction just after the bullet strikes. Now use 2 .

## What are the four variables at play with the kinematic equations?

These are the four variables at play with the kinematic equations. The equations describe the motion of an object that is subject to constant acceleration. By leveraging the equations, we can solve for the initial and final values of these variables. Displacement, velocity, and acceleration are all directional, whereas time is non-directional.

## What is the 3rd equation of motion?

Third Equation of Motion The third equation of motion relates to velocity, displacement, and acceleration. Using the same equation (2), S = x (v + u) x t

## How do you solve the equation of motion?

The equation of motion is: co k m dx mkxF dt ωω ω ω = = += 0 22 0 0 s . You should check that this is solved by putting cos (just subsitute into the equation and see!).
