Question
Answer
What is the Kinetic Energy formula?
Half mass x velocity squared (KE = 1/2mv^2)
What is the Force formula?
Mass x Acceleration (F = ma)
What is the Speed formula?
Distance / Time (v = d/t)
What is the Momentum formula?
Momentum is mass times velocity (p = mv)
What is the Density formula?
Density equals mass divided by volume (p = m/V)
What is Hooke's Law?
Spring force is negative of the spring constant multiplied by displacement (F_s = -kx)
What are the Power formulae?
Work/Time (P = W/t) Force x Displacement / Time (P = Fs/t) Force x Velocity (P = Fv)
What is the Gravitational Potential Energy formula?
Mass x Gravitational Force x Height (PE = mgh)
What is the Work formula?
Force x Displacement or distance (W = Fs)
What is the Distance formula?
Time x Speed (t*s)
What is the Velocity formula?
Displacement / Time (v¯ = s/t)
How can you calculate displacement as a function of average velocity and time?
s = v¯t
How can you calculate average velocity as a function of initial and final velocity?
v¯=1/2(v+u)
How can you calculate displacement as a function of final and initial velocities and time?
s = 1/2(v+u)t
How can you calculate final velocity as a function of initial velocity, acceleration and time?
v=u+at
How can you calculate final velocity as a function of initial velocity, acceleration and displacement?
v^2=u^2+2as
How can you calculate displacement as a function of initial velocity, acceleration and time?
s=ut+1/2at^2
How can you calculate average acceleration?
a¯=Δv/Δt (difference in velocity/difference in time)
How can you calculate average velocity?
v¯=Δx/Δt (displacement/difference in time)
How can you calculate elastic momentum?
m_1u_1+m_2u_2 = m_1v_1+m_2v_2
How can you calculate inelastic momentum?
m_1u_1+m_2u_2 = (m_1+m_2)v
