An object initially at x1 = 5.0 m changes its position to x2 = 12 m. What is the displacement of the object?

A graph of position (x) versus time (t) of a moving object s a straight line with a slope of 3.2 m/s. Which of the following is/are true of this object? (i)    The object has a uniform speed of 3.2 m/s (ii)   The moving object has no acceleration (iii)   The object has a uniform acceleration of 3.2 m/s2

One side of a cube is 10 cm. What is its volume in liters?

If a graph of force (F) acting on an object versus the acceleration (a) of the object is plotted with F on the y-axis and a on the x-axis, the slope of the graph will be a measure of:

A moving object is at x = 4 m at t = 0 and at x = 14 m at t = 2 s. The average speed of this object is:

Which of the following is/are true according to Newton’s second law? (i)    an unbalanced force always brings a moving object to rest (ii)   an unbalanced force on an object always produces an acceleration on it (iii)   the acceleration of a moving object is directly proportional to the unbalanced force acting on it.
