Momentum
kg x m/s is the units for
momentum
In every collision, momentum is
conserved
Force times radius gives you
torque
momentum can only be positive
false

A 6 kg object sitting on the ground has a momentum of
zero
If kinetic energy is conserved during a collision, what type of collision happened
elastic
How would you generate more leverage on a wrench?
apply the force further from the pivot point
momentum is always conserved
True
What star wars planet did Luke grow up on?
Tatooine
a 5 kg ball moving at 10 m/s has a momentum of
50 kg x m/s
What type of collision happens when two objects collide and stick to each other?
Completely inelastic collision
A force of 20 N applied from a distance of 1 meter will give you a torque of
20 Newton Meters
Kinetic energy is conserved in inelastic collisions
False
What is the 6th element on the periodic table?
Carbon
If a ball has a momentum of 100 kg x m/s and a mass of 10 kg, what is the balls speed?
10 m/s
A ball of clay hitting the floor would be what type of collision?
completely inelastic collision
A wrench has a torque of 100 Newton-Meters. If the force exerted was 100 Newtons, how long was the wrench? r=F/T
1 meter
To generate more torque, you should grab closer to the pivot point.
False
What is the capital of Germany?
Berlin
If an object is moving to the left, what is the sign of the object's momentum?
negative
In an inelastic collision, what is true of the kinetic energy?
It is only partially conserved/not fully conserved
Why are door handles on one side of the door?
you get more leverage/torque by pushing far away from the pivot point
The crumple zone in a car is designed to lengthen the time of impact, which lessens the force on the passenger.
True
What do you put into a toaster?
Bread
