State Newton?s second law of motion in terms of momentum. Calculate momentum given mass and velocity. The scientific definition of linear momentum is consistent with most people?s intuitive understanding of momentum: a large fast-moving object has greater momentum than a smaller slower object.

 

Linear Momentum quantifies the amount of motion an object possesses objects with larger masses or higher velocities have greater linear momentum. According to Newton's laws of motion an external force acting on an object can change its momentum resulting in acceleration or deceleration.

 

Newton actually stated his second law of motion in terms of momentum: The net external force equals the change in momentum of a system divided by the time over which it changes.

 

This Physics Tutorial will focus on the Laws of Motion Linear Momentum and Collisions. At the end of the tutorial you can download it for FREE. Please share this page with your friends who may need it. How well do you know Newton?s laws of motion Conservation of Linear Momentum and Collisions?

 

Here are the objectives for this lesson: Define linear momentum and impulse. Calculate the impulse on an object after it interacts with another object. State Newton?s laws of motion. Calculate the average force acting on an object after it interacts with another object over a given time interval.

 

By Newton's Second Law F=ma the conservation of linear momentum is supported. Since acceleration can be expressed as ?v/?t Newton's Second Law could therefore be expressed as F = m?v/?t.
