Term1/8

160j of work was needed in order to move an object 8m across a floor what was the force in N that was needed to do this job

Definition1/8

160j of work was needed in order to move an object 8m acroos a floor what was the force in N that was needed to do this job? i think it may be not sure but 20N dont agree with me just maybe your imput will be different

Term1/8

If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate

Definition1/8

constant speed

Term1/8

You set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the gro

Definition1/8

you set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the ground how much rope have you pulled through the pulley

answer is (10m)

Term1/8

With regard to the object-lifting examples traced in lesson3 the ima is equal to the distance divided by the distance

Definition1/8

it effort,resistance

Term1/8

A tortoise and a hare are running in a race you are asked to prepare graphs similar to those in your reading material to graph the progress of each animal during the race as in the text distance is t

Definition1/8

Term1/8

Near the end of page 124 of your reading material you are shown a calculation to determine a car's final speed after accelerating for four seconds

Definition1/8

There is a formula to calculate the speed of a car after accelerating for four seconds. This formula is v = u + at, where v = velocity, u = initial velocity, a = acceleration, and t = the time it takes to accelerate.

Term1/8

What is the effect of using an inclined plane to lift an object

Definition1/8

Term1/8

A graph shows distance on the vertical axis and time on the horizontal axisif the speed is steadily increasing what will the line representing speed look like on the graph

Definition1/8

If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
