PPT-Fun Side of Mechanics: Momentum (Collision) energy

By Jonathan Recap Last week we talked about countersteering What was countersteering Turn in the other direction in order to complete a turn A while back we mentioned velocity What was . . 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 . Physics. Problem #1. A 1500 kg car traveling +6 m/s collides with a 2000 kg truck at rest. The vehicles collide, but do not stick together. The car has a velocity of -3 m/s after the collision. What is the velocity of the truck after the collision? . (d)define . linear momentum as the product of mass and velocity. (e) define force as rate of change of momentum. (f) recall and solve problems using the relationship F = ma, appreciating. that acceleration and force are always in the same direction. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . I. . . Collisions. . II. . Work and Energy. Momentum:. an object of mass m, moving with velocity v has a momentum p = m v.. Momentum is an important and useful concept that is used to analyze collisions . . 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 . & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . Notes. Momentum Conservation Principle. One of the most powerful laws in physics is the law of momentum conservation. . For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects . 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. Corina. . Bot. , PhD (NJIT, C. 2. PRISM). Keri . Salvador (NJIT, C. 2. PRISM). Caroline . Savio. (ESHS, NPS). Career Day.

(m. ⋅. s. -1. ). momentum (kg. ⋅. m. ⋅. s. -1. ). Unit: kg⋅m⋅s. -1. Momentum is influenced by. 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. What factors affected how fast objects move after a collision? (Think of your lab). Section 1: Momentum and . Impulse. Linear Momentum:. Momentum is defined as . mass times velocity. .. Momentum is represented by the symbol p, and is 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..
