1 SECTION 2: FORCES AND DYNAMICS GOHS
IB SL PHYSICS: TOPIC 2 SECTION 2: FORCES AND DYNAMICS GOHS

2 Force, weight and mass Force is a pull or a push. For example:
Friction Normal or contact Tension & compression Air resistance weight

3 Force, weight and mass Weight is the pull of gravity on the mass.
Measured in Newtons (N) g = 9.8 ms-2 Is a force (a vector) Mass is amount of matter of an object Measured in kilograms (Kg) A scalar

4 Force, weight and mass On the Earth On the Moon Weight = 70 N
Clothes fit real good! On the Moon Weight < 70 N Clothes still fit real good!

5 Force, weight and mass Sample problem:
What is the weight of a 1.0 kg mass on the surface of the earth where g = 9.8 ms-2? W = mg

6 Force, weight and mass W = (1.0 kg) (9.8 ms-2) W = 9.8 N
