WebThe applied force converts the stored potential energy of the stationary object to kinetic energy to perform work. That’s why using the work-energy formula; we can calculate speed from force and mass. The work formula is, W= Fd. Since work done of an object is its gaining in kinetic energy KE= (1/2)mv 2. (1/2)mv 2 =Fd. WebExamples for effect of force. Force may bring the following change: 1) Can change the state of an object (rest to motion/ motion to rest):For example, pushing a heavy stone in order to move it. 2) May change the speed of an object if it is already moving.For example,catching a ball hit by a batsman. 3) May change the direction of motion of an ...

WebSince the molecules are moving much faster ~300m/s than the box (due to thermal vibrations) velocity will not affect how many molecules adhere (with the exception of "static friction"). However, static friction is sometimes be higher, in one explanation because the peaks have time to settle and interlock with each-other. WebNewton's first law says that if the net force on an object is zero ( \Sigma F=0 ΣF = 0 ), then that object will have zero acceleration.
