PPT-Momentum What is Momentum?

Momentum tendency of objects to keep going in the same direction with the same speed Depends on mass and velocity Has direction The momentum of a ball depends on its mass and velocity Ball B has more momentum than ball A.

Define and calculate the momentum of an object.. Determine the impulse given to an object.. . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . Linear Momentum. Momentum is a measure of how hard it is to stop or turn a moving object.. p. = m. v. (single particle). P . = . Σ. p. i . (system of particles). Problem:.

Estimate the amount of work the engine performed on a 1200-kg car as it accelerated at 1.2 m/s. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. Momentum is a quantity defined as the product of the mass and velocity of an object.. Unit of Momentum. The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction. What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.
