When a particle of mass 2kg starts moving from rest?

When a particle of mass 2kg starts moving from rest?

Expert-Verified Answer GIVEN:- A particle of mass 2kg starts moving from rest under the application of a single unidirectional force given as F = 8t, where t is time in seconds. Hence, the work done by the force on the body during the first 3 seconds of its motion is 144 Joules (J).

What is the energy of a particle moving 5m per second?

The energy of a particle moving at 5 m/s is 125 J.

What is the formula of moving mass particle?

He writes : m = mₒ / (1 – υ ²) ⅟² Guess where to put the missing c. A famous relation in physics relates ‘moving mass’ m to the ‘rest mass’ m0 of a particle in terms of its speed v and the speed of light, c. (This relation first arose as a consequence of special relativity due to Albert Einstein).

What is the formula for moving mass and rest mass?

Thus, the correct formula is m=m0√1−v2c2. Was this answer helpful? A famous relation in physics relates moving mass m to the rest mass m0 of a particle in terms of its speed v and the speed of light c. (This relation first arose as a consequence of special theory of relatively given by Albert Einstein).

Do faster moving particles have more energy?

The amount of energy a particle has depends on how fast it is moving. Faster-moving particles have more energy. Slower- moving particles have less energy. The particles in hot substances have more kinetic energy than the particles in cold substances.

What is the potential energy of a 2 kg particle moving?

The potential energy of the particle of mass 2 kg moving along the x-axis is given by U(x)=4x^2-2x^3 (where U is in joules and x is in meters).

What’s the formula for kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Why is rest mass of photon zero?

The photons are said to be chargeless and massless particles that travel at the speed of light. So the rest mass of a photon is taken to be zero. This can be proved from Einstein’s special theory of relativity. Hence the photons have a rest mass of zero.

Does mass increase with speed?

Another result of the theory of special relativity is that as an object moves faster, its observed mass increases. This increase is negligible at everyday speeds. But as an object approaches the speed of light, its observed mass becomes infinitely large.

What is the real formula of mass?

The different varieties of ways to determination of the mass of an object are there: (m= ρ/V) Mass = Density/Volume. (m=F/a) mass = force acceleration, the acceleration of an item is directly proportional to the force applied to it, according to Newton’s second law (F=ma).

What is rest mass equal to?

One of the terms in the relativistic kinetic energy equation is the rest-mass of the particle and its given by E=mc^2. The rest-mass energy is the energy that is stored inside a stationary particle as a result of its mass. Rest-mass energy implies that mass is simply another form of energy.

Is moving mass greater than rest mass?

Dynamics of moving object with the speed comparable to the speed of light is discussed in relativistic mechanics. The relativistic mass of a moving object is always greater than its rest mass.

What is Einstein formula for rest mass?

According to Einstein’s equation E=mc2. E represents the rest mass energy of an object with rest mass m,c is the speed of light in vacuum, and is given by 2.998×108ms.

What is a block of mass 2 kg initially at rest moves under?

A block of mass 2 kg initially at rest moves under the action of an applied horizontal force of 6 N on a rough horizontal surface. The coefficient of friction between block and surface is 0.1. The work done by the applied force in 10 s is (Take g=10 ms−2).

What velocity does a body of mass 2 kg starting from rest attains?

It acquires a velocity of 20 m/s in 4 seconds.

What is the law of moving a body of mass 2kg?

A body of mass 2kg travels according to the law x(t) = pt + qt^(2) + r… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… Displacement (y) of a body is represented by y = pt + qt^(2) – rt^(3)… A body of mass 2 kg is moving according to the equation for displaceme…

When a particle of mass 2 kg moves on a smooth horizontal plane?

A particle of mass 2kg moves on a smooth horizontal plane under the action of a single force→F=(3^i+^j)N. Under this force it is displaced from (0,0) to (1m,1m). The initial speed of the particle is √3m/s and final speed is √5km/s.
