When the egg hits the ground the forces of the impact are distributed around the shell so it does not break.
When comparing the momentum of two moving objects which of the following is correct?
TRUE – When comparing the momentum of two objects to each other, one must consider both mass and velocity; both are of equal importance when determining the momentum value of an object. When comparing the kinetic energy of two objects, the velocity of an object is of double importance.
Can a less massive object have more momentum than a more massive object?
A less massive object can never have more momentum than a more massive object. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have the greatest momentum.
Which of the following is a valid unit for momentum?
| Momentum | |
|---|---|
| SI unit | kg⋅m/s |
| Other units | slug⋅ft/s |
| Conserved? | Yes |
| Dimension | MLT−1 |
Why does an egg break when dropped on concrete?
The physics behind is called impulse and momentum. The egg falling has a momentum equal to it’s mass*velocity (downwards) .. to stop the egg you need to apply impulse in the opposite direction. Impulse is equal to the force * time during which the force is applied.
Why do egg break on concrete than grass?
When an egg is dropped on concrete, the surface of the concrete is harder than the grass. Due to the harder surface, the egg will break in a shorter time interval than if were dropped on grass. Grass will have the effect of an air bag so the time interval will be longer.
What happens when two moving objects hit each other?
When two objects collide, each object pushes the other. Newton’s third law states that when one object exerts a force on another, the second object exerts an equal but opposite force on the first object. These forces are sometimes called action force andreaction force or force pairs.
How does the total momentum of two objects before a collision compare with the total momentum after the collision?
For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
Can momentum be transferred?
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 a single object have kinetic energy but no momentum?
No , if a object has zero momentum then it doesn’t have kinetic energy because kinetic energy is half of linear momentum. where KE is kinetic energy and M is mass and V is velocity of the object.
What is momentum unit?
The units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s.
Why does the egg dropped on the road break?
In contrast, when the egg is dropped on the road, all of the force that is being applied by the road on the egg is in the tiny interval when the egg touches the road, That force is large enough to break the egg because it is being applied in a tiny amount of time. That’s why the egg dropped on the road breaks.
What type of force will break an egg?
A moderate force will break an egg. However, an egg dropped on the road usually breaks, while one dropped on the grass usually does not break. This difference is because for the egg dropped on the grass:
Why doesn’t the egg break when it lands on the grass?
That’s why the egg doesn’t break when it lands on the grass. In contrast, when the egg is dropped on the road, all of the force that is being applied by the road on the egg is in the tiny interval when the egg touches the road, That force is large enough to break the egg because it is being applied in a tiny amount of time.
