In which diagram would the block have the greatest acceleration?
A teacher performd a demonstration by pulling a bookshelf across the floor and measuring the force with a spring scale. While they pulled, a student measured the acceleration of the bookshelf using a device. The results are shown in the table.
When the class calculated the acceleration using the mass of the bookshelf and the amount of force the spring scale measured, the resulting acceleration was different from the actual acceleration that the device read. Which statement explains the difference between the calculated acceleration and the actual acceleration?
Another force in the direction of the motion produced a lower acceleration than calculated.
An opposing force caused by friction produced a lower acceleration than calculated.
Another force in the direction of the motion produced a higher acceleration than calculated.
An opposing force caused by friction produced a higher acceleration than calculated.
What is the acceleration?
The image shows a block that is being pulled along the floor. According to the image, what is the acceleration of the block? (a) m/s2
The motocylist currently has a greater acceleration than the car. Which changes would increase the acceleration of the car? Select TWO correct answers.
