Physics equations

• Acceleration= change in velocity/time
• What is the typical walking speed

  1.4m/s
• What is the typical running speed

  3m/s
• What is the typical cycling speed

  6m/s
• What is the typical car speed

  13m/s
• What is typical sound speed

  340m/s
• What is typical light speed

  300,000,000m/s
• If given 2 speeds you need to write out average of 2 speeds what is the equation


  Distance = (speed 1 + speed 2)÷time
• This is the equation to find uniform acceleration

  Final velocity^2 - initial velocity ^2 = 2 × distance x speed
• This is the letter equation find acceleration if have distance 


  V^2 - U^2 = 2 × a ×s
• How to calculate speed

  Speed(m/s) = distance(m) ÷ time(s)
• How to calculate velocity

  Velocity(m/s) = distance(m)/ time
• What is newtons force

  Force(N) = mass(Kg) × adceleration(m/s)^2
• Another way to write newtons second law is

  Force(N) = change in momentum(kgm/s) ÷ time(s)
• What is the equation for thinking distance. Stopping distance = braking distance + thinking distance
• What does force x distance equal to

  Force × distance = 0.5 × mass × (velocity)^2
• How to calculate momentum

  Momentum(Kgm/s) = mass(kg) ÷ time(s)
• How to calculate Gpe

  Gpe(J) = mass(kg) x gravity strength× change in height(m)
• How to calculate kinetic energy


  Ke(J) = 0.5 × mass(kg) × (velocity)^2(m/s)
• How to calculate wave speed

  Wave speed= frequency(Hz) × wavelength(m)
• Another way to calculate wave speed

  Wavespeed(m/s) = distance(m)÷ time(s)
• Frequency is the number of waves in 1 second it is measure in hertz. What is the equation


  Frequency(Hz) = number of waves ÷ time(s)
• The time period is the time time take for wave to pass a point. How do you calculate it?

  Time period(s) = 1 ÷ wave frequency(Hz)
