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

No work is taking place and no energy is moving outside of your body.
The movement of energy is all in your muscles, and it gets dissipated
as the sweat trickles out of your skin and evaporates into the air.
What is the mode of the windspeed of 40 kph?
The mode of the windspeed of 40 kph is 40 kph, as it is the value that appears most frequently in the dataset.
How is a heating curve used to relate to phase changes and temperature and kinetic energy?
A heating curve shows the relationship between temperature and heat added to a substance. During phase changes, the temperature remains constant as the added heat is used to break intermolecular forces. Kinetic energy increases with temperature, so during phase changes, the added heat is used to increase potential energy (for breaking intermolecular forces) rather than increasing kinetic energy (temperature).
This would require the knowledge of possible variables. Is body being displaced in terms of y? Is the body a projectile, shot by a spring? If the body is simply being pushed then the form of energy being shown would be Kinetic Energy (1/2mv^2).
How fast will a xr200 go top speed?
about 45-50mph depending on the year with some mods you can hit around 70mph
i would say about 50 mph but my 1982 Honda xr 100 goes about 55
1/2a(3.4)^2+[3.4a(a=0)](6.6)=100
[] is Vi and a in this case is 0 at it stops to accelerate when it gets to 3.4s
so a=100/(.5)(3.4)^2....=17.30
now Vf=(3.4*17.30)+17.30(6.6)...=173.01
How mach ve how many ne demek?
"How much" genellikle ölçülebilir miktarları sormak için kullanılırken, "how many" sayılabilir nesnelerin miktarını sormak için kullanılır. Örneğin, "How much water do you need?" suyun miktarını sormak için kullanılırken, "How many apples do you have?" elma sayısını sormak için kullanılır.
The conversion of potential energy in coal into kinetic energy that heats steam is an expression of the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or transformed. In this case, the potential energy stored in coal is transformed into kinetic energy in the form of heat to generate steam power.
At 55 MPH you need a gap of approximately how many seconds to pass safely?
To pass safely at 55 MPH, you should maintain a gap of around 4-5 seconds between your vehicle and the one you are passing. This allows you enough time and space to complete the pass without cutting off the other vehicle or risking a collision.
The average kinetic energy of 1 mole of water at 0 degrees Celsius is the same as at 298 K because temperature is a measure of average kinetic energy per molecule; it doesn't depend on the amount of substance. Therefore, the average kinetic energy remains constant for 1 mole of water.
The type of kinetic energy that is in the motion of a molecule is incredible Once it rises up, it comes down like a rocket falling towards earth except lighter. That's when it goes up. Once everything goes up, it must all come back down
What physical quantity the area under force-displacement graph represent?
It is the work done or the energy utilised
What was to top speed of the B-29 Superfortress?
The top speed of the B-29 Superfortress was approximately 358 mph (576 km/h).
How can displacement be negative?
Displacement is a vector quantity, which means it has a magnitude (size) and a direction, compared to a scalar quantity which only shows size. A negative displacement simply means that the person or object is going in a negative direction, or returning.
OR
Yes it can be -ve because with displacement, sign indicates direction. Usually right and up are designated as positive while left and down are designated as negative, but this can be changed as long as one is consistent.
So in most cases, if the displacement is negative it means you are moving in the opposite direction/backwards.
Degus are fast runners and can reach speeds of up to 15 miles per hour (24 kilometers per hour) when they are motivated or startled. They are agile and quick on their feet, which helps them escape from potential predators in the wild.
The coriolis component of acceleration is present in?
The Coriolis component of acceleration is present in rotating reference frames, such as the Earth's surface. It causes objects to veer to the right in the northern hemisphere and to the left in the southern hemisphere, as a result of the Earth's rotation. It is an inertial force that arises due to the motion of an object within the rotating frame of reference.
What is the speed of an object that travels 45 meters in 15 seconds?
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
What is the kinematic viscosity of Demineralised water?
The kinematic viscosity of demineralized water at 20°C is approximately 1.0 × 10^-6 m^2/s.
Compare and contrast refraction and reflection of wave energy?
Refraction is when light slightly bends because glass or water is in the way. This makes the object look bent or crooked. For example when you put a straw in a glass of water, the straw looks as if it were bent, but it really isn't. Reflection is when the light particles of an object bounce off of another object showing the same image. You can't see your reflection on all objects though.
How many RPMs does a 6 inch wheel spinning at 10 mph have?
A 6 inch wheel spinning at 10 mph would have approximately 786 RPM (Revolutions Per Minute). This calculation is done by converting the speed from mph to inches per minute (10 mph = 880 inches/min) and then dividing by the circumference of the wheel (6*pi = 18.85 inches).
Yes you can.
All you need to know is it's maximum height to find the total time.
We are not concerned with displacement because it's horizontal velocity is constant and there are no horizontal forces.
Let it's maximum height = h
It's vertical velocity at it's highest position = 0
Acceleration due to gravity = g
To find the time it takes the ball to come down from it's highest position can be calculated using the equation, s = ut + (1/2)at2 (Where s= displacement, u= initial velocity, a=acceleration and t=time)
=> h = 0 x t + (1/2)gt2
=> h = (1/2)gt2
=> t2 = 2h/g
=> t = √(2h/g)
The time it takes for the ball to go up is same as it is to come down because the acceleration is same for both the cases, hence the total time the ball remains in air will be 2t = 2 x √(2h/g)
