Explain.
Balloon B
has the greatest impulse. Impulse is equal to momentum change.
Which will experience the greater acceleration due to the collision?
In a collision, there is a force on both objects that causes an acceleration of both objects. The forces are equal in magnitude and opposite in direction, yet
the least massive object
receives the greatest acceleration.
Which object experiences the greatest acceleration?
The velocity change of each car is the same. (They start with the same velocity and each finish with zero velocity.)
Which vehicle experiences the greater force of impact?
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.
Where does the ball experience the greatest change in momentum?
The greatest change in momentum occurs
when the baseball is caught and thrown back
.
What are 2 ways to increase impulse?
2 ways through which the impulse can be increased are: 1)Increasing the force 2) increasing the time over which the force acts.
What is difference between momentum and impulse?
The momentum of the object is given by the product of mass and
velocity
while the impulse is the change of momentum when a large force is applied on an object for a short interval of time.
Which law relates acceleration to mass?
The BIG Equation
Newton’s second law of motion
can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
What is the law of acceleration?
According to
Newton s Second Law of Motion
, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
How Can acceleration be calculated?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation
a = Δv/Δt
. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
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.
Why do cars suffer more damage than the truck?
(d) Why is the car likely to suffer more damage than the truck? Answer : … (b)
Mass of truck is greater then mass of car and initial ad final velocity of car ad truck are same i.e., v ad 0 respectively
, therefore it will experience greater force of impact. Since, momentum is directly proportional to force.
Which case has the greatest velocity change?
The velocity change is greatest in
case B
. In each case the initial velocity is the same. In case B, the object rebounds in the opposite direction with a greater speed than in case A. This is equivalent to a change from +10 m/s to -5 m/s; whereas, case A has a change from +10 m/s to -2 m/s.
Which has the greater acceleration the bat or the ball?
The force that the baseball exerts on the bat and the force that the bat exerts on the baseball are the same magnitude. Which has the greater acceleration: the bat or the ball?
The ball because
it has a smaller mass than the bat.
Which case requires greatest impulse?
The impulse required is greatest
when the ball is caught and then thrown back
because the impulse required equals the change in momentum.
Which object experiences the greatest change in momentum?
The momentum change is dependent upon the velocity change;
the object with the greatest velocity change
has the greatest momentum change.
