If an object is moving at a constant speed the force of friction must equal the applied (horizontal) force, and for it to be accelerating or decelerating, the force of friction and the applied force must be unequal. Also, I know that f = μ N.

The object is moving without acceleration. Friction Friction is a force that acts in the direction opposite motion which occurs between two objects in contact. What causes objects to stop moving? Friction Between objects (Brakes on a car get hot) Between air and the object (Stick your hand out of a moving car window) Efforts to reduce friction:

A planet moving along an elliptical orbit is closest to the sun at a distance. A planet moving along an elliptical orbit is closest to the sun at a distance r1 and farthest away at a distance of r2. If v1 and v2 are the linear velocities at these points respectively. then the ratio v1/v2.

NCERT Question 10 An artificial satellite is moving in a circular orbit of radius 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth.Radius of the orbit = 42250 kmTime taken = 24 hoursDistance travelled by the satellite= Circumference of circle= 2𝜋r= 2 × 22/

An artificial satellite is moving in a circular orbit of radius 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth. Q. An artificial satellite is moving in a circular orbit of radius 42250 km .

In the case of a car moving around a circle with a constant speed, then we have uniform circular motion, but the velocity in this case is not uniform, it is changing direction. The word "uniform" in this case means it is travelling at a constant speed, and in such a case the magnitude of velocity is constant, but the direction changes.

1. A boy runs 200 metres in 24 seconds. What is his speed ? a) 20 km/hr b) 24 km/hr c) 28.5 km/hr d) 30 km/hr 2. If the speed of a man is 45 km per hour, then what is the distance traveled by him in 30 seconds ? a) 275m b)360m c)375 m d) 420 m 3. An escalator moves towards the top level at the rate of 11 ft.sec and its length is 140 feet.

a proton and an electron have the same kinetic energy if the mass of the proton is 1800 times the mass of the electron find the ratio of their de broy wavelengths where do we begin well since we're dealing with debris wavelengths we could probably start by de roy's wavelength equation we've seen already in previous videos the debris wavelength that is the wavelength associated with any object.

Find an answer to your question what percentage of kinetic energy of a moving particle is transferred to a stationary particle when moving particle strikes with… anshupriya81444 anshupriya81444 15.01.2021

A two-kilogram mass (something weighing 4.4 pounds on Earth) moving at a speed of one metre per second (slightly more than two miles per hour) has a kinetic energy of one joule. In the centimetre-gram-second system the unit of energy is the erg, 10 −7 joule, equivalent to the kinetic energy of a mosquito in flight.

F= V dm/dt = V (dm/dx)(dx/dt) = V^2 (dm/dx) Fdx = V^2 dm E = m v^2. ,mass flowing with constant velocity If velocity is changing rather than mass, then E.
