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

Term1/12

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

Definition1/12

constant speed

Term1/12

What the term deceleration means

Definition1/12

That means slowing down.

Term1/12

A screw is really an wrapped around a cylinder

Definition1/12

A screw is really an inclined plane wrapped around a cylinder.

Term1/12

Rate of deceleration are always expressed as

Definition1/12

Rates of deceleration are always expressed as negative numbers.

Term1/12

How far is the train located from its start after completing both movements if it goes forward at a speed of 1 ms for 20 seconds then stops and goes backward at a speed of 0.5 ms for 4 seconds

Definition1/12

The train has traveled along the track for 18 meters.

Multiplying and adding, the distance traveled is:

(1 x 20)m - (0.5 x 4)m

= 20 - 2

= 18

Term1/12

The most fundamental requirements for movement are a change in position

Term1/12

The graph at the top of the second column of page 122 shows a condition in which there is what

Definition1/12

no acceleration

Term1/12

If a car can go 0 to 60 mph in 8 seconds what would be its final speed after 5 seconds if its starting speed were 50 mph

Definition1/12

87.5mi/hr2

Term1/12

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

Definition1/12

Term1/12

How far is 13miles in minutes

Definition1/12

It is 26 minutes at 30 miles per hour to travel 13 miles in a car..

Term1/12
