Smooth surface
No friction
1 of 20
String is in-extensible
String does not change length, so accelerations and velocities of both particles, attached, are equal
2 of 20
Pulley is smooth
No friction, so tention is all parts of the string are equal
3 of 20
String/pulley is light
Adds no weight to the system, so acceleration is constant throughout the motion
4 of 20
Air projectile q's
Assume acceleration due to gravity is 9.8 (ignore air resistance)
5 of 20
Rod
Straight and doesn't bend, all forces remain perpendicular
