PHYS 1101: General Physics 1 Fall 2009 Formulas

Kinematics (linear motion)

slope = average speed =

Dynamics (linear motion)

(Newton’s 3^rd Law)

Circular Motion

Work and Energy

For conservative forces:

(power)

Momentum

Rotational Motion 1 revolution = 360⁰ = 2πrad

(angular speed) (linear speed)

(angular acceleration)

Torque and angular momentum

(moment of inertia where “ ” represents rotational inertia and depends upon shape of object)

(conservation of angular momentum)

Static Equilibrium

First condition: Second condition:

stress = F/A strain = ΔL/L₀ elastic modulus:

Fluids (static)

(density)

(Pascal’s principle) (buoyancy)

Fluids (moving)

(ρ= constant) (Bernoulli principle)

Waves

(SHM period) (pendulum period)

(speed in a string)

Standing waves strings: where n=1,2,3,….

open pipe: where n=1,2,3,….

Beats

Temperature and heat

(linear thermal expansion) (heat flow by temp difference)

Heat loss = heat gain (energy conservation) (latent heat during phase change)
