Momentum 1
A conceptual closed space in which some action occurs is known as this.
What is a system?
If a mass changes velocity over a long period of time, this is the effect on the force experienced by the mass.
What is a decrease in the force?
If a mass changes velocity over a short period of time, this is the effect on the force experienced by the mass.
What is an increase in the force?
In this, momentum is always conserved.
What is a closed system?
The idea that momentum is always constant is known as this.
What is the Law of Conservation of Momentum?
The product of mass and velocity of an object is known as this.
What is momentum?
In a collision where two objects collide and then stick together, the resulting velocity after the collision will be this.
What will be less?
N∙s is equal to this unit.
What is kg∙m/s?
Momentum has this unit.
What is kg∙m/s?
One reason momentum is a vector is for this reason.
What is momentum is calculated using velocity, which is a vector?
This is the reason why heavier rifles kick less.
What is their greater mass results in a smaller velocity?
Impulse is equal to this.
What is the change in an object’s momentum?
A system where both the object exerting the force and the object receiving the force are inside is known as this.
What is a closed system?
The force inside a system is known as this.
What is an internal force?
In a collision where two objects collide and then stick together, the resulting momentum after the collision will be this.
What is equal to prior to the momentum prior to the collision?
The variable used to represent momentum is this.
What is p?
The units for impulse are these.
What is N∙s or kg∙m/s?
An object stopping suddenly will experience this.
What is a large impulse?
Impulse is represented by these two variables.
What are Ft?
Force multiplied by the time it is applied is known as this.
What is impulse?
The Law of Conservation of Momentum is an extension of this natural law.
What is the Law of Conservation of Energy?
The delta or triangle in a mathematical equation means this.
What is change?
The momentum of an object before a circumstance is equal to this.
What is the momentum after?
This is the reason an egg landing on a mattress has less of a chance of breakage.
What is the force applied to the egg is spread over a large time?
Momentum is considered to be this.
What is a vector?
