Kinematics
Kinematics is the study of how a body moves. This includes linear motion, angular motion, and rotational motion.

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.
Why is spark produced when two stones are stricken against one another?
When stones are stricken against one another, then there are chances of transfer of electrons from one to the other. So positive in one and negative charges in the other are produced. Now comes a chance to have an electrical discharge between them which leads to produce sparks in air.
How much distance is covered accelerating to 60 mph in 7.2 secs from a stop?
If accelerating to 60 MPH in 7.2 seconds from a stop you would go 3 miles. This is considered a math problem.
The goose has a mass of 20.1 and is flying at 9.60mph. What is the kinetic energy of the goose?
KE=1/2mv^2
make sure it is in kilograms/meters^2
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:
MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.
How fast is a horse traveling in miles per hour if he is going 525 meters per minute?
525 meters per minute equates to 19.57 mph
Business and residential areas have a speed limit of mph?
Different countries - and even different cities within the same country - have different speed limits.
Kinetic friction is associated with thermal energy (and sound or light).
How to find potential energy when only mass and velocity time is given?
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.
What is position - time graph?
- A position-time graph, is one in which position is plotted on the y-axis and the time is on the x-axis. A position-time graph is similar to a distance-time graph, but direction of motion in the y-axis.
Which type of energy is being converted into kinetic energy as a marble falls from a shelf?
Gravitational Potential Energy, also known as GPE.
As both marbles are free-falling under gravity both have the same acceleration, g or 9.81ms-2
What does potential and kinetic energy have to do with paper airplanes?
It all started when a guy named ken base jumped off a cliff with a flying fox
Work-kinetic energy theroem expression?
When work is done on a body its kinetic energy changes.Let a constant force F acting on a body of mass m changes its velocity from u to v in a distance d, then work done = F * d
change in kinetic energy = 1/2mv2 - 1/2mu2 = 1/2m(v2 - u2) =1/2m * 2ad =ma * d =F *d
Therefore work done = change in kinetic energy, that is F *d = 1/2mv2 - 1/2mu2.
How is the potential energy stored in the spring of a clock it change into kinetic?
The spring is wound tighter, this stores the potential energy. The spring unwinding turns the potential energy into kinetic energy.
How many seconds would it take to travel 15 feet at 3.5 feet per seconds?
15 feet ÷ 3.5 ft/s = 4.29 s.
What is 462 miles in hours while driving 60 miles per hour?
It will take about 7 hours and 40 minutes of total driving time at a constant 60 mph. Your total travel time will be longer if you slow down or stop along the way.
What does slope of the graph of v vs t represents?
ski
You don't state what the letters stand for, but if velocity (or more accurately, speed) and time then the gradient (dv/dt where "d" means "difference in") will give the acceleration.
At constant speed the line will be horizontal so the gradient will = 0, i.e, neither acceleration nor deceleration.
Top speed of a doodlebug dirt bike?
it goes 15-17 factory setting but if you adjus the speed gov. you an make it go up to about 35 or 30
