Physics Equations

Question 1

Position-Displacement Equation

Answer 1

Δx = x(final) - x (initial)

Displacement (Δx) is the distance between the final position and initial position

Question 2

Average Velocity Equation

Answer 2

V (avg) = Δx/Δt

The average velocity is equal to the change in x over the change in time

Question 3

Instantaneous Velocity Equation

Answer 3

v =lim Δx/Δt
Δt->0

Instantaneous velocity (v) is the derivative of position with respect to time, representing the velocity at a specific moment.
​

Question 4

Acceleration Equation

Answer 4

a = Δv/Δt

acceleration is the change in velocity of the change in time

Instantaneous acceleration is what you get when the change in time approaches zero
or you take the derivative of the velocity with respect to time

Question 5

Equation of Motion

Answer 5

Δx = v(i)t + (1/2)a(t)^2

Question 6

Velocity acceleration time relationship

Answer 6

v (f) = v(i) + at

Question 7

Projectile Range Equation

Answer 7

Range = (v^2(i) * sin (2ø))/ g

Question 8

Projectile Time of Flight Equation

Answer 8

T = 2v(i) sin(ø)/g

Question 9

Projectile Maximum Height Equation

Answer 9

H = (v^2(i)sin^2(ø))/2g
