PHYSICS EQUATIONS QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
Displacement (d) - ANSWER d = Δx = final position - initial positon = net distance (plus direction)



Average velocity (v) - ANSWER v = Δx/Δt = d/Δt



Average acceleration (a) - ANSWER a = Δv/Δt



What assumption do we make with the BIG 5 equations? What are the 3 most frequently used
equations? - ANSWER That acceleration is constant (uniformly accelerated motion)



2. Missing d

3. Missing vf (v final, v)

5. Missing t



BIG 5:



1. Missing a - ANSWER d = ½(v₀ + v)t



BIG 5:



2. Missing d - ANSWER v = v₀ + at



BIG 5:



3. Missing v (v final) - ANSWER d = v₀²t + ½at²



BIG 5:

, 4. Missing v₀ - ANSWER d = vt - ½at²



BIG 5:



5. Missing t - ANSWER v² = v₀² + 2ad



For projection motion, we assume that the downward direction is... - ANSWER NEGATIVE direction.



DOWNWARD = NEGATIVE DIRECTION.



PROJECTILE MOTION - Horizontal Motion

(in the x-direction)



Give the equation for:

1. Displacement

2. Velocity

3. Acceleration - ANSWER 1. d = v₀t (in the x-direction)



2. v₀x = vx (velocity is CONSTANT in the x-direction!!)



v₀x = v₀cosθ₀



3. ax = 0 (acceleration in the x-direction is ZERO!)



PROJECTILE MOTION - Vertical Motion



Give the equation for:

1. Displacement

2. Velocity
