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 experiences the greater impact force?
Which vehicle experiences the greater force of impact? Answer: A From Newton’s 3rd Law of action-reaction.
Which vehicle will experience a 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 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.
Which vehicle experiences the greater change in acceleration?
Which vehicle experiences greater acceleration greater? The Honda experiences greater de-acceleration because it has less mass. Newton’s 2nd law (F=ma) can be rewritten to read a=F/m. For the same force the acceleration is inversely proportional to the mass.
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.
Which car undergoes the greater change in 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 vehicle experiences the greater change in momentum 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.
What is the law of conservation of momentum state?
Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.
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 are padded dashboards safer than hard dashboards in automobiles?
Padded dashboards make automobiles safer because they increase the time taken to decrease the momentum of an impacting body to zero, which decreases the impact. Thus, the force acting on the padded dashboards is small.
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.
What happens if one of the cars collided with more force than the other one?
Forces between two colliding objects
It doesn’t matter if one car is heavier (more massive) than the other. The push force from one car will equal the push force from the other.
