the area bounded by the line and the axes of a velocity-time graph is equal to the displacement of an object during that particular time period
Thank you
a substance's density is the same at a certain pressure and temperature, and the density of one substance is usually different than another substance.
Average speed = total distance traveled/total time taken
it is the total distance traveled in a total time the total distance is attained
1) B. Energy is the ability to do work
2) C. Energy is conserved, it just goes from one form to another.
3) Work = Force x displacement
= 300 x 100 = 30,000 Joules
4) leaning a brick because no displacement is taking place.
5) They change the amount/strength or direction of the force needed.
6) Less force is needed and applied over a longer distance.
7) Heat is the flow of thermal energy from one object to another.
