MDCAT Physics key points fsc part 1. Students in their first year of physics who are studying for the FSC and MDCAT should pay attention to the important points listed below each unit.

## MDCAT Physics Key Points:

Here are some sample key points from Fsc part 1.

• A central force is one that is incapable of producing torque.
• Two equal and opposite force acting along the same line of action will result in translational as well as rotational equilibrium.
• When two or more than two forces acting on a common point, the forces are called concurrent forces.
• If a metallic bob is suspended by a string in the vertical plane, it will be in complete equilibrium.
• When three forces acting at a point are in equilibrium, then each force is numerically greater than the difference of the two.
• The minimum number of forces that keep the body in equilibrium are 2.
• Whenever there is spin motion then force will act away or towards the centre.
• Total weight of a body acts at its centre of gravity.

• Real and apparent weight becomes equal in inertial frames, static frames and frames moving with uniform velocities.
• A couple produces rotational motion.
• More viscous mobile oils are used in motorcycles in summer than in winter because viscosity decreases with increase in temperature.
• When a paratrooper attains a terminal speed then drag force is equal to weight.
• At terminal velocity acceleration is zero.
• In cold region we prefer an engine oil of low viscosity.
• A small and a large rain drops are falling through air then large drop moves faster.
