In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity.
14 wrz 2024 · Momentum (p) is the product of an object’s mass (m) and its velocity (v). Its formula is: p = m × v. Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the object’s velocity.
28 lip 2023 · Learn what momentum is, how to calculate it, and how it relates to force and impulse. See solved problems on momentum of objects with different masses and velocities.
11 lis 2024 · We expand our understanding of interactions by introducing momentum and angular momentum, complementing our focus on energy. The chapter explores how forces impact changes in linear and rotational motion, applying concepts like torque and impulse to analyze interactions.
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 \[p = mv \nonumber\] where \(m\) is the mass of the system and \(v\) is its velocity.
The SI unit for momentum is kg m/s. Momentum is so important for understanding motion that it was called the quantity of motion by physicists such as Newton. Force influences momentum, and we can rearrange Newton’s second law of motion to show the relationship between force and momentum. Recall our study of Newton’s second law of motion (F ...
