Terms Definitions
Suppose you jump from a high perch does flexing your legs increase the stopping time and reduse the stopping force? True
The concept of change in momentum is? impulse
What happens in Inelastic They stick together
The net force acting on a body is equalto the rate at which the body's quantity of motion is changing original version
What is the SI unit of momentum? kilogram-meter per second (kg*m/s)
Two objects collide and bounce off each other Elastic Collisions
In the absence of external forces the momentum of a system remains constant Conservation of momentum
The net force acting on a body is equal to the product of the body's mass and its acceleration the perverted version
What is the representation of impulse? letter J
it is the product of an object's mass and velocity Momentum
Impulse cannot be described mathematically in many ways false
Impulse is not the rate of change in momentum but the total chage in momentum. true or false? true
What happens in Elastic They bounce off each other
since momentum is a vector .. is impulse a vector too? true
Can a momentum of an object change significantly by a large force if the force acts over the a long period of time? false
A collision in which a body stick together on colliding and proceed thereafter with a common velocity is side to be perfect inelastic Perfect Inelastic Collision
Impulse can be described mathematically in many ways true
Any collisions in which the total kinetic energy is not conserved is called an _______ Inelastic collisions
M1V1 + M2V2 = M1V1' + M2V2 momentum BEFORE = momentum AFTER
EF=ma the perverted version
Newton's "quantity of motion" is what we now call? Momentum
it is equivalent to the newton-second law(N*s) kilogram-meter per second (kg*m/s)
Suppose you jump from a high perch does flexing your legs decrease the stopping time and reduse the stopping force? false
momentum is a vector .. impulse is not True or false? false
Can a momentum of an object change significantly by a small force if the force acts over the a long period of time? true
Is the original version of the law different from the perverted one?why? no new rules we simply have a new way of stating newton's second law
Can a momentum of an object change significantly by a large force if the force acts over the a short period of time? true
Two objects collide and stick together Inelastic Collisions
When is this use "M1V1 + M2V2 = M1V1' + M2V2'" Elastic and Inelastic Collisions
One object separates into two fragments Explosions
What are the 3 types of collisions? Elastic Collision Inelastic Collision and Perfect Inelastic Collision
Change in momentum of an object that is caused by a force acting on a object for some period of time impulse
An _____ collision is one in which the total KE as well as the total momentum of the system is conserved Elastic Collision
EF=^p/^t original version
momentum BEFORE = momentum AFTER Conservation of momentum
Can a quick change in momentum and a slow change in momentum can involve the same impulse? True
Can a momentum of an object change significantly by a small force if the force acts over the a short period of time? false
