Do objects with the same momentum have the same velocity? Step 1. a) textbf{a)} a) As velocity is a vector quantity, it is important in which direction the object moves. The momentum moments are the same, the velocity vectors must also be equal, not only in intensity but also in direction. So, the answer is:
Yes, these objects have the same directions
.
Does same momentum mean same velocity?
Same momentum means that the large mass must have a small velocity
(so that their product is equal to the small mass times a large velocity).
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and
directly proportional to the object’s velocity
.
What happens if two objects with the same momentum collide?
Will all vehicles moving at the same speed have the same momentum?
Momentum is the mass of an object multiplied by its velocity.
A moving truck has more momentum than a car moving at the same speed
because the truck has more mass. A fast car can have more momentum than a slow truck. A truck at rest has no momentum at all.
How can a tennis ball and a bowling ball have the same momentum?
After if there are any changes, they must be the same, otherwise the total momentum is not constant. So,
the tennis ball will change velocity more, but it has less mass
, so it can have the same momentum change as the bowling ball, which will not affect velocity much but has a bigger mass.
Can two objects have the same momentum but different kinetic energies?
4 Answers. Show activity on this post. So,
if two objects have the same energy Ek, they only have the same momentum if they also have the same mass
. Since the bull has a much larger mass than the bullet, it must therefore have a much larger momentum than the bullet to arrive at the same kinetic energy.
Does momentum affect velocity?
Mass and velocity are both directly proportional to the momentum
. If you increase either mass or velocity, the momentum of the object increases proportionally.
What happens to the momentum when objects have the same velocity but different mass?
Momentum is a conserved quantity; the momentum of an object is never changed. The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed;
the more massive object will have the greatest momentum
.
Momentum is directly proportional to mass and velocity
. Describe the relationship between mass velocity and momentum. The greater the mass and velocity the greater the momentum. The impulse on an object is equal to the change in momentum.
What happens to velocity when two objects collide?
Momentum and Common Velocity
Momentum is equal to the mass of the object multiplied by its velocity
. In any collision, whether it is elastic or inelastic, the total momentum of the system before the collision must be equal to the total momentum of the collision after the collision.
What happens when two cars collide at same speed?
“Although the two-car crash doubles the speed,
the energy the crash is transferred to twice the mass resulting in a crash that looks like just one car hitting a wall at 50 mph
.”
When comparing the momentum of two moving objects which of the following is correct?
When comparing the momentum of two moving objects, which of the following is correct?
The object with the higher velocity will have less momentum if the masses are equal
.
Will two objects with the same mass always have the same momentum?
Two objects with the same mass will always have the same momentum
.
Which has more momentum a heavy truck or a light truck?
Q. Which has more momentum, a heavy truck moving at 30 km/hr or a light truck moving at 30 km/hr? Cannot be determined.
They both have the same momentum
.
Which has more momentum if it moves twice as fast?
1. A moving car has momentum. If it moves twice as fast its momentum is
twice as much
.
Which has more momentum a stationary bowling ball or an identical rolling bowling ball?
The answer is
BOTH balls have momentum
as both balls are moving!
When the velocity of an object is doubled its momentum?
If the velocity of a body is doubled then
its momentum doubles
because velocity is directly proportional to the momentum.
Which has more kinetic energy tennis ball or table tennis ball?
Can two objects with different masses have the same velocity?
Explanation: When an object is under free fall, its acceleration depends only on the acceleration due to gravity and mass has no role to play. Due to this;
irrespective of their masses, the object under free fall with have the same velocity at any instant
.
Why does velocity decrease after collision?
When a matter collides there is a transfer of momentum collectively and not the velocity as a single component.
If a heavy mass strike a smaller mass then the collective momentum increases but collective velocity decreases.
Is momentum the product of mass and velocity?
momentum,
product of the mass of a particle and its velocity
. Momentum is a vector quantity; i.e., it has both magnitude and direction.
What does momentum Tell us about an object?
What is the difference between velocity and momentum?
What is the difference between momentum and velocity?
Momentum is dependent on mass, and velocity is independent of mass
. The momentum is conserved in a closed system, but the velocity is not conserved. An external force is always required to change the velocity, but momentum can be changed by changing mass.
Can objects with different masses Cannot have the same momentum?
Objects with different masses can’t have the same momentum
. Direction does not matter when you are measuring momentum. Momentum can be transferred from one object to another.
Does an object moving at constant speed have momentum?
An object which is moving at a constant speed has momentum
. An object can be traveling eastward and slowing down; its momentum is westward. Momentum is a conserved quantity; the momentum of an object is never changed. The momentum of an object varies directly with the speed of the object.
What is the relationship between an impulse on an object and the change in momentum of that object?
The impulse experienced by the object equals the change in momentum of the object
. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
Which statement correctly compares the influence of velocity on kinetic energy and momentum?
Which statement correctly compares the influence of velocity on kinetic energy and momentum?
The momentum of an object is proportional to the object’s velocity, and the kinetic energy of an object is proportional to the square of the object’s velocity.
Which of the following is true if the momentum of an object changes and its mass remains constant?
Is velocity the same after collision?
Is velocity conserved in a collision?
An inelastic one-dimensional two-object collision. Momentum is conserved, but internal kinetic energy is not conserved. (a) Two objects of equal mass initially head directly toward one another at the same speed. (b) The objects stick together (a perfectly inelastic collision), and so
their final velocity is zero
.
What is the relationship between momentum and collision?
Do both cars always change speed by the same amount in A collision?
Consider your example of a collision between identical cars traveling at 60 mph. They cannot each receive a 120-mph impact—in opposite directions! Instead, they share the combined “120-mph crash.” And as their masses and speeds are the same, they share it equally:
Each vehicle receives a 60-mph impact.
When 2 vehicles collide momentum is conserved?
In collisions between two objects momentum is conserved.
Since the initial momentum is not zero, the final momentum is not zero
. Both objects cannot be at rest. It is possible for one of the objects to be at rest after the collision.
What determines if one car has more momentum than another in A two car collision?
An object has a large momentum
if either its mass or its velocity is large
. Thus, a fast-moving car has more momentum than a slow-moving car, if they have the same mass.
How can a tennis ball and a bowling ball have the same momentum?
After if there are any changes, they must be the same, otherwise the total momentum is not constant. So,
the tennis ball will change velocity more, but it has less mass
, so it can have the same momentum change as the bowling ball, which will not affect velocity much but has a bigger mass.
