Quick Answer: Can The Momentum Of An Object Change?

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..

What happens when two objects with different mass collide?

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. … Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

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.

What happens immediately after a skydiver opens her parachute?

What happens immediately after a skydiver opens his or her parachute? and why? The air resistance greatly increases and the skydivers speed decreases. The parachute opens up and doesnt allow the air to flow through it, which is air resistance. Fluid friction acting on an object moving through the air.

How does mass affect speed?

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

Is momentum conserved in an explosion?

Whether it is a collision or an explosion, if it occurs in an isolated system, then each object involved encounters the same impulse to cause the same momentum change. The impulse and momentum change on each object are equal in magnitude and opposite in direction. Thus, the total system momentum is conserved.

Is it true that the momentum of an object can change?

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.

What affects the momentum of a moving object?

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. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.

Does momentum change in a collision?

In a collision, the momentum change of object 1 is equal to and opposite of the momentum change of object 2. … Yet, the total momentum of the two objects (object 1 plus object 2) is the same before the collision as it is after the collision. The total momentum of the system (the collection of two objects) is conserved.

What happens to the momentum of an object during a collision?

Momentum is of interest during collisions between objects. When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum.

Which object has the greatest acceleration?

Object C has the greatest acceleration. It is the only object with an acceleration. Accelerated motion on a p-t graph is represented by a curved line.

How can you increase the momentum of an object?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

How do you know if momentum is conserved?

The momentum of an object will never change if it is left alone. If the ‘m’ value and the ‘v’ value remain the same, the momentum value will be constant. The momentum of an object, or set of objects (system), remains the same if it is left alone. Within such a system, momentum is said to be conserved.

Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

In what direction is acceleration if an object is slowing down?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

Will two objects with the same mass always have the same momentum?

Momentum is not equal to the mass of an object divided by its velocity. … Two objects with the same mass will always have the same momentum.
