Calculate momentum of a particle having mass 28kg and velocity 7.8ms?
The momentum of a particle is given by the formula p = mv, where p is the momentum, m is the mass, and v is the velocity. Substituting the values, we get momentum = 28 kg * 7.8 m/s = 218.4 kg m/s.
What is the difference between a small momentum and a large momentum?
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
Two identical cars are travelling along edsa having the same velocity .which of two vehicles would have greater momentum?
Both cars would have the same momentum since momentum depends on both mass and velocity, and in this case, the cars have the same velocity and mass. So, the momentum of both cars would be equal.
Can somthing have momentum without having energy?
momentum = mass * velocity kinetic energy = 1/2 mass * velocity^2 If an object has non-zero momentum, it has non-zero velocity. It thus has kinetic energy, at least. It most likely has other forms of energy as well (potential, thermal, etc.)
When does a car have momentum?
Momentum = Mass x Velocity. (p=m*v)The mass of an object made of matter can not be zero.If the object (car) is moving, then the velocity will be non-zero, and the object will have non-zero momentum.So, if you are driving or rolling the car, it has momentum.If it is parked, then it will have 0 velocity (with respect to the earth), and thus will have 0 momentum.So, when the car is moving, it has net momentum. When it is parked it has zero momentum. I then just becomes a mater of semantics whether having zero momentum is equivalent to not having momentum, or if it is actually a valid value for momentum or state of momentum.
Can a body have kinetic energy without having momentum?
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
Why do you need momentum?
Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum
Which object in table 3-1 has the greatest momentum?
The object with the greatest momentum in table 3-1 is the truck, which has a mass of 8000 kg and a velocity of 20 m/s. Momentum is calculated by multiplying an object's mass by its velocity, so the truck's momentum would be the product of these values, which is 160,000 kg*m/s.
Tennis ball have momentum?
Momentum is calculated by taking the product of mass times velocity. Thus, a moving tennis ball would have a nonzero momentum. However, since a tennis ball has a relatively small mass, it would need to have a high velocity in order to have a large value for its momentum. Since velocity is a vector (having both a magnitude and a direction), momentum is also a vector. When a tennis player hits a tennis ball with his racket, he imparts a force onto the tennis ball, which changes the direction of its momentum to return it over the net. (The value for this change in momentum is called impulse, which is equal to the product of the force applied and the time for which it is applied.)
Can abody have energy without having momentum?
yes. a body can have energy without momentum also. consider a body at a height 'h' m above the ground level , potential energy contained is = mgh but , as the velocity is 0 we can consider that the momentum of the body is 0
Can a body have momentum without having energy?
Any mass can be expressed in terms of energy, according to the famous formula, E=mC^2.Thus, any mass (m), having a momentum will always have some energy associated with it.
Does a particle moving in a straight line have acceleration?
A particle moving in a straight line may or may not have acceleration. Acceleration is adifferent phenomenon altogether. the rate of change of velocity is acceleration, a particle can move in a straight line with a constant velocity thus having no acceleration & it can also move with increasing or decreasing velocities thereby accelerating or deaccelerating.
