BALANCED & UNBALANCED Forces Force involves either a PUSHor a PULL act between objects How to convert = 50 Kg your mass (Kg) to weight (N)? Force We can identify different forces acting on objects. Identify the force/s acting on the object. pushing force hand on the pen; pen on the paper Identify the force/s acting on the object. pulling force arm on the projector screen Force can be measured using a force measurer. Spring Balance is a force measurer. It stretches according to the amount of force applied. Spring Balance is a force measurer. It stretches according to the amount of force applied. Force is measured in newton (N). We can also determine the amount of force acting on objects. 300 N 500 N Two boys pulling the rope to the left and three girls pulling the rope to the right Weight is the measure of how strong gravitational force is acting on an object. How to convert = 50 Kg your mass (Kg) to weight (N)? = 50 Kg F = m x g or m F = kg xs2 2 EARTH = 10 m/s Identify the force/s acting on the object. PULLING FORCEis done by the two blue men and one red man on the rope. Balanced Force Effect: no movement Direction: none Net Force: 0 N Unbalanced Force Effect: with movement Direction: to the left Net Force: 50 N Force come in pairs may be BALANCED or UNBALANCED Effe cts o f F or c es Effect: change in size and shape 50 N Direction: downwards 20 N Net Force: 30 N FORCE CAUSES CHANGE IN...
