A passenger sitting in the rear of a bus claims that he was injured when the driver slammed on the brakes after a dog jumped out in front of the bus, causing a suitcase to come flying toward the passenger from the front of the bus. If you were the judge in this case, would you believe him?
In Case A an object is moving straight downward with a constant speed of 9.80 m/s, while in Case B an object is moving straight downward with a constant acceleration of magnitude 9.80 m/s2. Which one of the following is true?
Homework Answers
1)correct- It is possible to have forces on an object in the absence of motion of the object.It is possible for an object to have motion in the absence of forces on the object.
2)correct-no i dont believe him because after brakes it should not move to the back but towards the front
3)a nonzero net external force acts on the
object in Case B only, this is correct becauseit has
acceleration

Which of the following are Newton's laws of motion? Select all that apply. Question options: A object in equilibrium will remain so unless acted upon by an outside force. The normal force on a body equals mass times gravity (N=m*g) For every action, there is an equal and opposite reaction The sum of external forces on a body equals mass times acceleration (F= m*a)

The following objects all have a net force of zero Newtons and are therefore in equilibrium. In each case some forces acting on the object are provided. Discuss the total number of forces acting on the object and add the missing forces. You may elect to choose from the provided list of forces, but feel free to discuss/provide a force that is not listed, if you feel your explanation is better. List of possible forces: Weight (The pull of gravity)...
