What is the momentum of a 20 kg body moving with a velocity of 10 m per second?
What is the momentum of a 20 kg body moving with a velocity of 10 m per second?
Hence the momentum of the body is 200 kg. m/s.
What is the speed of a 1.0 x10 3 kilogram car?
A 1.0 × 10³-kilogram car travels at a constant speed of 20 meters per second around a horizontal circular track.
What is the formula for momentum velocity?
p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.
What is the formula for momentum upon velocity?
The quantity of motion is measured as a product of the mass and the velocity. The product of the units of mass and velocity is the unit of Momentum. To find the momentum, we can use the simple formula: P=mv, where P is the momentum.
What is the formula for the centripetal acceleration?
The acceleration is directed radially toward the centre of the circle. The centripetal acceleration ac has a magnitude equal to the square of the body’s speed v along the curve divided by the distance r from the centre of the circle to the moving body; that is, ac = v2/r.
What is the speed of an object of 1 kg mass with a kinetic energy of 50 J?
Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J. ∴ The correct option is the 4th.
What is the acceleration of a car with a mass of 1 200 kg?
In this case, the mass of the car and the force exerted on it are provided as information. Therefore, the acceleration of the car is 0.5 m s−2 when its engine exerts a force of 600 N .
What is the SI unit of momentum?

Other units | slug⋅ft/s |
Dimension | MLT−1 |
What is P in physics?
p = momentum m = mass v = velocity The definition of momentum. It is conserved (constant) if there are no external forces on a system.
What is P total in physics?
For a mixture of ideal gases, the total pressure exerted by the mixture equals the sum of the pressures that each gas would exert on its own. This observation, known as Dalton’s law of partial pressures, can be written as follows: P (total) = P ₁ + P ₂ + P ₃ + …
What is V in momentum?
Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt).
What is the 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).
Does velocity mean speed?
Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.
What is the change in momentum of a body of mass 20 kg moves with an acceleration of 2 meters per second square?
Rate of change of momentum of body is 40 N. Q.
What is the momentum of a body of mass 10 kg moving with a velocity of 5m sec?
Answer: The linear momentum of a body of mass 10 kg moving with velocity 5 m/sec is 50 kg m/s.
What is the change in momentum of a body in 0.01 second is 10 kg Metre per second?
The force acting on a body is equal to rate of change of momentum. Change of momentum = 10 Kg/s, time taken = 0.01 second. Force = 10/0.01 = 1000N.
What is the momentum of a body of mass 10 kg if the body is at rest?
Explanation: Answer: Therefore, the momentum of a body of mass kg if the body is at rest is zero.
