When two vehicles moving at the same rate of speed are involved in a collision, the
vehicle that weighs less
will take the greater impact; the larger and heavier the vehicle, the greater the energy and momentum.
Which vehicles undergoes the greater change in its motion?
Which vehicle undergoes the greater change in its motion, and why? — same force on each;
bike
undergoes greater change in motion because of its much smaller mass 58.
Which car will experience the greater change in momentum?
The Beetle
would have the greatest change in momentum because this car has a lesser mass, causing it to travel at a faster velocity after the collision.
Which vehicle experiences the greater change in momentum and which experience greater acceleration?
Since, momentum is directly proportional to force. (c)
Car
will have greater acceleration as for force of impact is same and mass of car is less than mass of truck.
Which vehicle is likely to suffer more damage and why?
(c) As acceleration = force/mass, and force on each vehicle is same, acceleration As mass of car is smaller, therefore, acceleration of car is greater than the acceleration of the truck. (d) The car is likely to suffer more damage
than the truck
, as it is lighter.
What is impulse equal to?
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 case has the greatest momentum change?
The momentum change is dependent upon the velocity change;
the object with the greatest velocity change
has the greatest momentum change.
What factors does momentum depend on?
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. where m is the mass and v is the velocity.
What is the force required to stop a moving object?
Explanation:
an external force
is required to stop a moving object because the external force creates a sort of friction or a blockage for the moving object helping it to stop.
What determines the outcome of a collision?
Apart from the properties of the materials of the two objects, two factors affect the result of impact:
the force and the time during which the objects are in contact
.
Which experiences the greater impact force?
When two vehicles moving at the same rate of speed are involved in a collision, the
vehicle that weighs less will
take the greater impact; the larger and heavier the vehicle, the greater the energy and momentum.
Which vehicle experiences the greater change in acceleration A car B truck C both D none?
(b) Since, both truck and car are moving with the same magnitude of velocity v, momentum change for both vehicles is same. (c) Mass and acceleration are inversely proportional to each other. Therefore,
car
experiences greater acceleration due to its smaller mass.
Is momentum transferred in collisions?
Momentum is
simply transferred from one object to the other object
. Put another way, it could be said that when a collision occurs between two objects in an isolated system, the sum of the momentum of the two objects before the collision is equal to the sum of the momentum of the two objects after the collision.
Can momentum be created?
The conservation of momentum states that, within some problem domain, the amount of momentum remains constant;
momentum is neither created nor destroyed
, but only changed through the action of forces as described by Newton's laws of motion.
How is momentum conserved when two trailer trucks collide head on?
Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. … In the collision between the truck and the car,
total
system momentum is conserved.
Why is J used for impulse?
In words “impulse causes a change in momentum”. Maybe because the use of the letter “J” to
represent a quantity whose name begins with the letter “I”
is so odd, this relationship is usually written in its expanded form… In a way, this is a nice convention since now we can see the equivalence of units a bit more easily.
