What is momentun?
Momentum is a measure of an object's motion, determined by its mass and velocity. It describes how difficult it is to stop an object in motion, with larger momentum requiring more force to alter the object's speed or direction. The formula for momentum is: momentum = mass x velocity.
What is the impulse momentum theorem?
The impulse momentum theorem states that the change in momentum of an object is equal to the impulse applied to it. Mathematically, it is represented as FΔt = Δp, where F is the force applied, Δt is the time over which the force is applied, and Δp is the change in momentum of the object. This theorem is useful in analyzing collisions and calculating the effects of forces on objects.
What is physical significance of linear momentum?
The same as momentum - sometimes called "linear momentum" to distinguish it from angular momentum. Linear momentum is the product of mass times velocity. It is a conserved quantity, making it very useful for certain calculations.
Why is the law of inertia for rotating system in terms of angular momentum?
The law of inertia for rotating systems is described in terms of angular momentum because angular momentum is conserved in the absence of external torques, similar to how linear momentum is conserved in the absence of external forces according to Newton's first law. This conservation of angular momentum provides a useful way to analyze and understand the motion of rotating systems.
What is Impulse momentum?
Impulse momentum theory: when force is applied to a rigid body it changes the momentum of the body. it is calculated with respect to time and also the velocity is calculated.
When is momentum not useful?
when you are skiing down a hill and you want to slow down
Why is the law of conservation of momentum useful in analyzing the collision between two bodies?
The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.
Which two theories would be useful in designing a roller coaster?
gravity and momentum

What does it meanto say that momentum is conserved?
Momentum is the product of mass times velocity. The sum of (momentum x velocity) for all parts of a closed system remains constant. For instance, if two balls collide, any momentum lost by one is gained by the other (transferred to the other). Energy is NOT necessarily conserved (kinetic energy, to be more precise - any energy lost will be converted into heat, usually), so momentum is sometimes more useful for certain calculations.
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
What Does it Men To Momentum is Conserved?
When momentum is conserved, the initial momentum is equal to the final momentum.
