A constant unbalanced force is applied to an object for a period of time. Which graph best represents the acceleration of the object as a function of elapsed time?
The diagram shows a horizontal 12-newton force being applied to two blocks, A and B, initially at rest on a horizontal, frictionless surface. Block A has a mass of 1 kilogram and block B has a mass of 2 kilograms. The magnitude of the acceleration of block B is
6.0 m/s²
2.0 m/s²
3.0 m/s²
4.0 m/s²
Which body is in equilibrium?
a satellite moving around Earth in a circular orbit
a cart rolling down a frictionless incline
an apple falling freely toward the surface of Earth
a block sliding at constant velocity across a tabletop
The diagram represents two concurrent forces. Which vector below represents the force that will produce equilibrium with these two forces?
In the diagram below, a 20-newton force due north and a 20-newton force due east act concurrently on an object, as shown in the diagram below. The additional force necessary to bring the object into a state of equilibrium is
20 N, northeast
20 N, southwest
28 N, northeast
28 N, southwest
A man standing on a scale in an elevator notices that the scale reads 30 newtons greater than his normal weight. Which type of movement of the elevator could cause this greater-than-normal reading?
accelerating upward
accelerating downward
moving upward at constant speed
moving downward at constant speed
Two forces, F1 and F2, are applied to a block on a frictionless, horizontal surface as shown below. If the magnitude of the block’s acceleration is 2 m/s2, what is the mass of the block?
