 Newton's First Law of Motion In the absence of any unbalanced applied force (Fnet = 0), a body at rest remains at rest and a body in motion continues in motion with the same velocity. Inertia The natural tendency of an object to maintain its state of rest or uniform velocity. The natural tendency of an object to maintain its state of rest or uniform velocity. Inertia In the absence of any unbalanced applied force (Fnet = 0), a body at rest remains at rest and a body in motion continues in motion with the same velocity. Newton's First Law of Motion Newton Kg M s^-2 SI unit of Force SI unit of Force Newton Weight The amount of gravitational force exerted by Earth on an object. The amount of gravitational force exerted by Earth on an object. Weight Formula for weight w = mg Newton's Second Law ΣFx = m*ax and ΣFy = m*ay Where ax and ay are the accelerations in direction x and y respectively. Newton's Third Law of Motion For every force(action) that acts on an object there is an equal and opposite force (reaction). For every force(action) that acts on an object there is an equal and opposite force (reaction). Newton's Third Law of Motion Equation for the normal force of an object on an incline plane at angle Θ N = mg cos(Θ) N = mg cos(Θ) Equation for the normal force of an object on an incline plane at angle Θ The 3 types of friction Static Friction, Sliding (kinetic) Friction, and Rolling Friction Force of static friction Fs = μ N Where μ is the coefficient of static friction and N is the normal force Force of Kinetic Friction Fk = μ N Where μ is the coefficient of kinetic friction and N is the normal force
