4 seconds later it is traveling at 2 m/s. 2 A 3 kg object is going 5 m/s at t= 0 secondsĮ.g.2 A 3 kg object is going 5 m/s at t= 0 seconds. ![]() Suppose a 10 kg object is being accelerated by a 10 N force. Suppose a 10 kg object is being accelerated by a 10 N forceĮg. This results in the formula Fnet = Fa +Ff (recall that Ff like all force is a vector, so it being in the opposite direction will have a – sign associated with it.)ħ eg. Each is pulling with 75 N Fnet = F1 + F2 Fnet = Fnet = 150 NĦ In real situations, friction is often a force that reduces the applied force (Fa) 2: This time Johnny and Billy are pulling on a sledĮx.2: This time Johnny and Billy are pulling on a sled. 1 Johnny and Billy are playing tug – o – warĮx.1 Johnny and Billy are playing tug – o – war. ![]() The Net Force not the “dark side” of the forceĢ The Net Force In the expression F = ma, the a can be interpreted as the total resultant acceleration which a body receives when acted upon by some total force whose magnitude and direction are given by F.ģ Since force is a vector quantity, the total force acting upon an object is the vector sum of the separate forces that are acting.
