Physics 1425 Midterm 1 Question and
answers rated A+ 2025/2026
Average Velocity - correct answer ✔v = ∆x/∆t
Instantaneous Velocity - correct answer ✔v = dx/dt
Instantaneous Acceleration - correct answer ✔a = dv/dt
Distance moved at a constant acceleration - correct answer ✔x(t) = x0 + v0t + 1/2a(t^2)
Constant Acceleration - correct answer ✔x = 1/2a(t^2)
Projectile Motion - correct answer ✔r = v0t = 1/2g(t^2)
Hang Time - correct answer ✔t = 2v0y/g
Range - correct answer ✔R = v0x(t) = 2(v0x)(2v0y)/g
Rmax - correct answer ✔Rmax = v0^2/g
Newton's First Law - correct answer ✔An object at rest stays at rest and an object in motion stays in
motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's Second Law - correct answer ✔F=ma
