... • Does its velocity change by regular amounts each second that it’s falling? If yes, why; if no, why not? • Yes, changes by ten for every second the object falls • Is the distance it falls per second the same amount each second? Explain why. • No, as it falls it gets faster so for every second it fa ...

... ⇒ Usually many forces act on an object at the same time. The net force, the combination of all of the forces acting on an object, determines whether the velocity of the object will change. ⇒ Balanced forces – forces acting on an object that combiner to produce a net force equal to zero ⇒ Unbalanced ...

... b) Again, from the balance of the cart, a=(F-f)/m, so the acceleration does not change. A constant applied force does not necessarily produce a constant acceleration. Because the acceleration does not only depend on the applied force, but also depends on the friction and the mass. c) From the equat ...

Newton`s Laws Notetakers
... Newton’s Laws of Motion FORCE Newton stated that the change in velocity of an object is caused by FORCES. When the velocity of an object is constant, or if the object is at rest, it is said to be in equilibrium. Contact forces: forces that result from physical contact between two objects. Examples: ...

Sliding Mass Problems
... Draw a force diagram and label the known information for each problem. Use your diagrams to write a valid equation for Newton’s Second Law and solve for the unknowns. You will need to use other equations (form Chapter 5) to solve. 1. A loaded snow sled is pulled by six huskies with a force of 1,250 ...
