Can a body at rest have momentum?
Any object at rest has 0. Rest objects do not possess momentum. They do not possess any "mass-in-motion". In comparing momentum between two objects, both variables - velocity and mass - are crucial.
It is also important to understand the linear momentum of a resting body.
Zero is the linear momentum of a body that is at rest. Explanation: A body at rest will have zero velocity. Linear momentum is mass x velocity.
What are some examples for momentum? A bowling ball, which is large in mass and moves slowly (low velocity), can have the same momentum as an ordinary baseball that is thrown quickly (high velocity). Another example of a bullet where momentum is extremely-very high is due to its extraordinary velocity is
It is also important to understand if a body can have momentum but not possess energy.
Yes, energy can be stored in a body without it possessing momentum. An body might have potential energy but cannot be still at rest. It would therefore have zero momentum but it might still possess energy. E.g. E.g.
What is the body doing when it's at rest?
Rest in Physics is an object that is stationary relative to another object or frame of reference. A body is considered "at rest" when its position with respect to its surrounding objects does not change over time.

What is the difference between momentum and linear momentum?
The main difference between linear momentum and angular momentum is that linear momentum is a property of an object which is in motion with respect to a reference point (i.e. any object changing its position with respect to the reference point) while angular momentum is a property of objects which are not only changing
How does force relate to momentum?
Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.
What is the SI unit of impulse?
Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg⋅m/s).
What are the units of linear momentum?
Linear momentum (momentum for brevity) is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s.
What is the impulse momentum theorem?
When an object has a momentum , and a force is applied for an amount of time, the momentum can change to a new value . The impulse-momentum theorem states that the impulse is equal to this change in momentum. Momentum is equal to the mass times the velocity of an object ( ).
Is linear momentum a scalar or a vector quantity?
Momentum is a vector quantity. For a particle with mass, the momentum equals mass times velocity, and velocity is a vector quantity while mass is a scalar quantity. A scalar multiplied by a vector is a vector.
What is the mathematical formula expressing Newton's second law of motion?
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
What's the difference between momentum and kinetic energy?
An important difference is that momentum is a vector quantity - it has a direction in space, and momenta combine like forces do. Kinetic energy is a scalar quantity - it has no direction in space, and kinetic energies combine like "regular numbers."
Can an object have momentum if mechanical energy is zero?
Zero mechanical energy means that there is no potential energy and no kinetic energy. Therefore, if kinetic energy is zero, velocity becomes zero and hence, there will be no momentum. The Brainliest Answer! Yes, An object can have momentum even If its mechanical energy is zero.
Is momentum a energy?
Momentum and Energy are very distinct physical quantities. Whenever you have momentum, there will also be energy of motion. Energy is a scalar having only a magnitude. All momentum is mass times velocity.
Can a body have energy without having momentum and have momentum without having energy explain?
Yes, possible. For an object staying at height h from the ground possess a potential energy of mgh. But it's momentum is zero since it's at rest.
In which motion does momentum change but kinetic energy does not?
In uniform circular motion linear momentum changes but kinetic energy does not. This is because in circular motion, linear velocity keeps on changing at each and every point as it is a vector quantity.
Does an object having energy always has momentum?
Yes, an object with momentum always has energy. If the object has momentum (mv) it must be moving, and if it is moving it has kinetic energy. No, an object with energy does NOT always have momentum. Since this object's velocity = 0, its momentum is zero.
What are the two types of momentum?
In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops.
What is the difference between momentum and impulse?
Momentum is mass in motion, and any moving object can have momentum. An object's change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it's the increase or decrease of an object's momentum.
What is an example of an impulse?
Impulse is a certain amount of force you apply for a certain amount of time to cause a change in momentum. That is why it is F*t. For example, when you hit a ball with a cricket bat, you apply a force for a time(a very short period in this case) to cause a change (or transfer) of momentum in the ball.
What are some examples of inertia?
Examples of Inertia
- One's body movement to the side when a car makes a sharp turn.
- Tightening of seat belts in a car when it stops quickly.
- A ball rolling down a hill will continue to roll unless friction or another force stops it.
- Men in space find it more difficult to stop moving because of a lack of gravity acting against them.
