Why Is Momentum Not Conserved? Momentum is not conserved if there is friction, gravity, or net force (net force just means the total amount of force). What it means is that if you act on an object, its momentum will change. This should be obvious, since you are adding to or taking away from the
Why Is Momentum Conserved? When a collision occurs in an isolated system, the total momentum of the system of objects is conserved. Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. Why is momentum always
Why Is Momentum Not Always Conserved? Momentum is not conserved if there is friction, gravity, or net force (net force just means the total amount of force). What it means is that if you act on an object, its momentum will change. This should be obvious, since you are adding to or taking away from
Can The Law Of Momentum Conservation Ever Be Violated? Conservation of momentum is violated only when the net external force is not zero. But another larger system can always be considered in which momentum is conserved by simply including the source of the external force. Is momentum ever not conserved? Momentum is not conserved if
Do All Objects With Mass Have Momentum? Momentum can be defined as “mass in motion.” 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
Why Does Direction Matter For Momentum? Momentum is not only dependent on the mass and speed of the target. In a given direction, velocity is distance, so an object’s momentum therefore depends on the direction of motion. This means that an object’s velocity will shift whether the object accelerates or slows down. How does change
Can A Slow Object Have More Momentum Than A Fast Object? The amount of momentum an object has depends upon how much mass it has and fast that mass is moving. The faster an object moves, the more momentum which it has. The slower an object moves, the less momentum an object has. Can something
Is Momentum The Same In Both Directions? For a collision where objects will be moving in 2 dimensions (e.g. x and y), the momentum will be conserved in each direction independently (as long as there’s no external impulse in that direction). In other words, the total momentum in the x direction will be the same
How Can You Prove That Angular Momentum Is Conserved? The linear momentum and angular momentum of the body is given by →p=m→v and →l=→r×→p about an axis through the origin. The angular momentum →l may change with time due to a torque on the particle. ∴→l = constant, i.e. →l is conserved. Is the momentum
When An Impulse Is Applied To A Moving Object What Is The Object’s Momentum? Impulse and momentum have the same units; when an impulse is applied to an object, the momentum of the object changes and the change of momentum is equal to the impulse. Does a moving object have momentum? All moving objects have
