Objects that are moving possess momentum. The amount of momentum possessed by the object depends upon how much mass is moving and how fast the mass is moving (speed). Momentum is a vector quantity that has a direction; that direction is in the same direction that the object is moving.
Learn about momentum in physics. Get its definition, units, formula, and worked example problems. See how it relates to Newton's laws.
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.
Momentum is a quantity involving the motion of an object. Objects with greater mass naturally have high momentum, but this will also depend on velocity. Suppose a car and a truck move on the highway with the same velocity.
Learn about and revise momentum, conservation of momentum and the relationship between force and momentum in collisions with GCSE Bitesize Combined Science.
Force and momentum are intimately related. Force acting over time can change momentum, and Newton’s second law of motion, can be stated in its most broadly applicable form in terms of momentum. Momentum continues to be a key concept in the study of atomic and subatomic particles in quantum mechanics.
Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
When we refer to a force being “exerted on a system”, we mean exerted on one or more of the particles in the system. In particular, the sum of the work done by internal forces is not necessarily zero, so energy and momentum are thus conserved under different conditions.
Momentum in physics is the vector product of mass times velocity and is denoted by p: p = mv. The law of conservation of momentum states that in a closed system, total momentum of the system before an event (such as a collision) is the same as total momentum after the collision occurs.
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.
