What is a sentence using the word 'acceleration'?
Acceleration is a change in velocity per unit of time.
How do lorries reduce the pressure on the ground?
Increase the number of wheels and/or increase the tread width of the tires or tracks, so that their weight is distributed over a larger area.
How fast in mph is 32 feet per second?
There are 3600 seconds in one hour. Therefore, 32 feet per second is equal to 32 x 3600 = 115200 feet per hour.
There are 5280 feet in one mile. Therefore, 115200 feet per hour is equal to 115200/5280 = 21.81 recurring (that is, 21.818181...) miles per hour.
How many hours will it take to travel from champaign Ill to Carbondale Ill traveling at 60 mph?
It will take 3 hours 19 minutes.
What effect will balanced force have on a book?
If the forces are balanced, this implies that the net force on the book is 0. Therefore, using Newton's second law, F = ma, F = 0, and since the mass of the book is non-zero, a = 0. This means that the book is not accelerating in the direction of these forces. However, this DOES NOT mean that the book is stationary; it could be travelling at any CONSTANT velocity (since there is no acceleration).
Surface speed refers to the velocity of an object at its surface, typically measured in units like meters per second or kilometers per hour. It can apply to various contexts, such as the speed of a vehicle moving along a road, the rotational speed of a spinning object, or the flow rate of a fluid at the surface. Surface speed is important in fields like physics, engineering, and transportation, as it helps assess performance and safety.
The formula half the mass times the velocity squared is used to calculate what type of energy?
that is kinetic energy
How long does it take to go 492.8 feet at 30 mph?
It would take approximately 8 seconds to travel 492.8 feet at a speed of 30 mph.
Is speed always measured by miles per hour?
No. Speed can be measured in other ways as well, such as km per hour and meters per second.
How do you find meters per second from kilometers per hour?
1 kilometer per hour = 5/18 meters per second = 0.2777....78 Deriving: 1 kmph means ... In 3600 seconds [60 min x 60 sec] object is moving 1000 meters [1 km] So, In 1 second it moves is obviously 1000/3600 = 5/18 meters Therefore 1 kilometer per hour = 5/18 meters per second -------------------------------------------------------- 1 kilometers per hour = 0.277777778 meters per second. i got it from google calculator
When force is to the direction of motion no work is done?
No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.
Is biomass energy potential or kinetic?
Biomass energy is a form of potential energy, as it is stored in organic materials such as plants and animal waste. When this biomass is burned or converted into other forms of energy, it is transformed into kinetic energy that can be used to power various applications.
