INTRODUCTION•Newton's equation of motion:F = maFOR M₂(total of slotted masses on hanger)•3 force acting on m₂- force from the contact of the frictionless surface- the contact force and the gravitational force - the tention in the stringFOR m1•2 force acting- the gravitational force - the tention

PROCEDURES:1. The linear air track air set was assembled as shown2. switch on the pump and let the air blow through the track for several minutes. The track have been balanced by adjusting the screws on the legs of the track, so that the glider stays stationary and does not glide to either end when let go1. insert one hook at one end and a flag on top of the glider2. the mass of the hanger and the lenght of the flag was recorded3. one end of the string was attached to the hanger and the other end to the glider.
