Is it possible for an object with a negative acceleration to be speeding up? If so, give an example. If not, explain why not.
Yes, if the direction of velocity is also negatvie, then the object will accelerate.

is it possible for an object to have zero velocity but non-zero acceleration? If so, give an example from your experiments. In any case, explain why. A motion diagram might help.
a) b) and c) all have negative or positive and is skateboarder speeding up or speeding down. Answer the following questions: a) In the picture above, the velocity is pointing in the [Select ] direction and the acceleration is pointing in the Select ] direction. Therefore the skateboarder is Select ] b) In the picture above, the velocity is pointing in the Select] in the [Select ] skateboarder is Select ] direction and the acceleration is pointing dirtion Thfor: th...
Which of the following velocity-versus-time graphs represents an object that is speeding up at a uniform rate of acceleration? V V V
FIGURE 1.19 One of these objects is speeding up, the other slowing down, but they both have a positive acceleration ay (a) Speeding up to the right (b) Slowing down to the left 2. Consider Figure 1.19 in the textbook. As stated in the figure, the Δ 1 min between snapshots. (Note: you will need to estimate the position values; do this with some care.) a. (15 pts) Choose the correct word (positive, negative, or zero) to describe the direction...
(a) Can the kinetic energy of an object be negative? If no, explain, if yes, give an example. (b) Can the potential energy of an object be negative? If no, explain, if yes, give an example.
Velocity and acceleration problem Help please An object moves clockwise around the track shown in the diagram below. The instantaneous velocity and the instantaneous acceleration of the object when it is at point A are shown. a) Draw and label on the diagram above arrows to represent the direction and magnitude of the parallel and perpendicular components of the instantaneous acceleration of the object at point A. b) Is the object slowing down, speeding up or does it have constant...
Could u please solve all? Give me some good reasons for these questions (1) Can an object have a velocity with zero acceleration? Can an object have acceleration with zero velocity? Explain why or why not Explain why the acceleration should be the same for each trial despite the distances changing. (3) An object moving to the right has a positive acceleration which is decreasing. Is this object speeding up or slowing down? Explain why. Give a full description of...
Is it possible to have a non-zero net force on an object that does no work on the object? if not, explain why. if so, provide an example.
your acceleration was in the positive or negative direction. You may have to adjust the axes to see the needed features. Once you get a good graph, study it until you can answer this question: Acceleration graphs are typically "noisy," but you have to at least be able to tell What was the sign of the acceleration while you were speeding up while moving away? Use the definition of acceleration to show how you arrived at this answer Explain why...
