p=v/m
p=m+v
The SI unit for momentum is:
kg/m
N/m
kg·m/s (or N·s)
J/s
Which statement best defines impulse?
The product of mass and velocity
The product of force and time interval
The ratio of force to time
The product of kinetic energy and time
Which equation correctly relates impulse and change in momentum?
J=p
J=F+Δt
J=FΔt=Δp
J=F/Δt
A collision is best described as:
An interaction where forces act for a long time and momentum is not conserved
An interaction where forces act for a short time and momentum is conserved
A situation where kinetic energy is always conserved
Any motion where objects move in the same direction
In an inelastic collision, which statement is correct?
Momentum is not conserved, but kinetic energy is conserved
Both momentum and kinetic energy are conserved
Momentum is conserved, but kinetic energy is not conserved
Neither momentum nor kinetic energy is conserved
In a perfectly inelastic collision, what happens?
Objects bounce off with the same speed
Objects stick together after collision
Kinetic energy is fully conserved
Momentum becomes zero in all cases
Why do airbags reduce injury during a crash?
They increase the force on the head
They decrease the mass of the driver
They extend the impact time, reducing the impulsive force
They stop the car instantly
