Only its acceleration would be westward.į.
If the object is slowing down, its momentum is still eastward. If an object is traveling eastward, then it has an eastward momentum. FALSE - The direction of an object's momentum vector is in the direction that the object is moving. However, one should be quick to note that the object does not have to have a constant speed in order to have momentum.Į. When that inertia is in motion, the object has momentum.ĭ. FALSE - An object has momentum if it is moving. The kg m/s is the standard unit of momentum.Ĭ. FALSE - The Joule is the unit of work and energy. Momentum, like other vector quantities, is subject to the rules of vector operations.ī. Like all vector quantities, the momentum of an object is not fully described until the direction of the momentum is identified. An object with a changing speed will have a changing momentum.Ī.The forward moving object will have the greatest momentum. Two identical objects are moving in opposite directions at the same speed.A less massive object can never have more momentum than a more massive object.Two objects of different mass are moving at the same speed the more massive object will have the greatest momentum.The momentum of an object varies directly with the speed of the object.Momentum is a conserved quantity the momentum of an object is never changed.
An object can be traveling eastward and slowing down its momentum is westward.An object which is moving at a constant speed has momentum.An object with mass will have momentum.The standard unit on momentum is the Joule.Which of the following statements are true about momentum?
