Answer:
Speed and direction of motion is velocity. ... A change in speed is a change in velocity – so, a change in speed is an example of acceleration!
Measure
Remember that velocity includes the speed and direction of an object. Therefore, a change in velocity can be either a change in how fast something is moving or a change in the direction it is moving.
Answer:
2. kinetic energy = total energy - potential energy
Explanation:
The total energy of a system is the addition of kinetic and potential energy of the system. Kinetic energy can be regarded as form of energy posses by an object when it's in motion
Total energy = kinetic energy + potential energy
(If we make Kinectic energy the subject of the formula, we have)
kinetic energy = total energy - potential energy
.001g = 1 mg
.000001g=1μg
You can get the idea,
410 mg/day=410,000 μg/day
just move the zero over in the positive direction 3 times.
I think it should be D. Because the potential energy of a roller coaster is at its lowest point or is the least at the bottom of the lowest point in the roller coaster. It is at its greatest at the top of the highest point of the roller coaster. Hope this helps! =^-^=
Answer:
Explanation:
in some reactions we see this as a change in the temperature. ... The study of energy changes (particularly heat) in chemical reactions is known as ... When a chemical reaction occurs, bonds in the reactants break, while new bonds form in the product. ... Physical changes can also be classified as exothermic or endothermic.
