What happens when two objects with the same momentum collide?
For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
That is, the momentum lost by object 1 is equal to the momentum gained by object 2..
Which if either has greater momentum a 1 kg ball moving at 2 m/s or a 2 kg ball moving at 1 m s?
Which if either has a greater momentum: a 1-kg moving at 2m/s or a 2-kg bad moving at 1 m/s. Which has a greater kinetic energy? Same momentum, but different KE. The 1-kg ball traveling at 2 m/s has a greater KE.
What does force equal to?
According to NASA, this law states, “Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.” This is written in mathematical form as F = ma. F is force, m is mass and a is acceleration.
What is momentum in real life?
Momentum in a simple way is a quantity of motion. … If an object does not move then it has no momentum. However, in everyday life it has an importance but many people didn’t recognize it. Momentum is just about every activity that involves motion. It is an essential concept of physics.
Can a single object have a kinetic energy and no momentum?
No , if a object has zero momentum then it doesn’t have kinetic energy because kinetic energy is half of linear momentum. where KE is kinetic energy and M is mass and V is velocity of the object.
What has a momentum of zero?
So momentum equals mass times velocity or p = m x v. Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero. Examples of Momentum: … A 1000 kg car moving at 15 m/sec has a momentum of 15,000 kg•m/sec as a result of multiplying the mass and the velocity.
Can a lighter object have more momentum than a heavier one how?
Question: Can A Lighter Object Have More Momentum Than A Heavier One? … No, Because Momentum Is Independent Of The Mass Of The Object.
Do heavier objects fall faster?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.
Why do heavier objects go further?
The heavy object will feel small changes to its speed (its acceleration is close to zero), while the light object will slow down a lot (its acceleration is a large negative number). In the end, the heavy object will travel farther, since it was less affected by air resistance.
Is momentum conserved in a closed system?
1) Closed system – A closed system does not interact with its environment so there is no net external impulse. The total momentum of a closed system is conserved. That is, the total momentum of the system remains constant.
When would an object have zero momentum?
The momentum of any object that is at rest is 0. Objects at rest do not have momentum – they do not have any “mass in motion.” Both variables – mass and velocity – are important in comparing the momentum of two objects.
What condition must be satisfied for the total momentum of a system to remain constant?
A system must meet two requirements for its momentum to be conserved: The mass of the system must remain constant during the interaction.As the objects interact (apply forces on each other), they may transfer mass from one to another; but any mass one object gains is balanced by the loss of that mass from another.
Why do stationary objects have no momentum?
Total momentum is always conserved between any two objects involved in a collision. … The stationary object encounters the greater collision force. A moving object collides with a stationary object; the stationary object has significantly less mass. The stationary object encounters the greater momentum change.
Under what conditions would the change in momentum be zero?
An isolated system is defined to be one for which the net external force is zero (Fnet = 0). During projectile motion and where air resistance is negligible, momentum is conserved in the horizontal direction because horizontal forces are zero. Conservation of momentum applies only when the net external force is zero.
Can a tiny bullet have more momentum than a huge truck?
Momentum is not equal to the mass of an object divided by its velocity. The momentum of an object can change. Two objects with the same mass will always have the same momentum. … A tiny bullet can have more momentum than a huge truck.
Is momentum can be negative?
Momentum can be negative. Momentum is a vector quantity, meaning it has both magnitude and direction.
Does Momentum have direction?
Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.
Is momentum conserved when a ball bounces?
conservation of momentum: The amount of momentum in a system remains the same after a collision. elastic collision: A collision in which all of the momentum is conserved. For example, a ball that bounces back up to its original height. … momentum: Mass in motion.
