Why is the car likely to suffer more damage than the truck?
(d) The car is likely to suffer more damage than the truck, as it is lighter. The acceleration, i.e., change in velocity of car is more than that of the truck.
Why are heavy vehicles usually of low velocity but possess high kinetic energy?
The car has a lower mass, so it must have a higher velocity in order to have the same momentum as the truck. But since kinetic energy depends upon the square of the velocity, the higher car velocity matters much more than the lower mass.
Why does it take a large truck longer to stop than a compact car?
The truck has more mass thus, more momentum. So the truck needs a larger force to stop it. why does it take a large truck longer to stop than a compact car, even though both are traveling at the same velocity? a fast moving car has a greater velocity and more momentum than a slow moving car of the same mass.
Can a small car have the same momentum as a large truck?
Is it possible for a small car to have the same momentum as a large truck? Yes, the small car would have to be moving with a much higher velocity, but it can have the same momentum since momentum is mass times velocity.
Which truck will experience the greatest 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 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.
Which will have the greatest impact on kinetic energy?
Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.
Does a car’s kinetic energy change more when the car speeds up from 10 to 15 m/s or from 15 to 20 m/s explain?
Answer and Explanation: The kinetic energy changes more if the car goes from 15 m/s to 20 m/s.
Why does a fast moving car have more momentum?
Why does a fast moving car have more momentum than a slow-moving car of the same mass? Because faster objects have more momentum than slow objects. … Some of all of the momentum from the first object is transferred to the second object.
What usually happens to momentum when objects collide?
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.
What does the law of conservation of momentum say?
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.
Which of the two cars would be more difficult to stop?
Answer: A supertanker has an enormous mass so, with any velocity at all, its momentumwill be very large and it will require a force acting over a very long time to bring it to a stop.
Can a small light ball have the same momentum as a large heavy ball?
5) A heavy object and a light object have the same momentum. … Reasoning: Momentum = mass x velocity. Thus if two objects have the same momentum, the lighter object will have a larger velocity.
Which has more momentum a huge moving truck or a small moving toy cart Why do you say so?
Answer: Momentum is owned by a moving object. A large truck that doesn’t move means it’s at rest, so the speed is 0.
