1
Q
Elastic Collision
A
A collision in which total kinetic energy is conserved
2
Q
Inelastic Collision
A
A collision in which total kinetic energy is not conserved
3
Q
Impulse
A
Force acting for a certain time causing a change in the object’s momentum
Impulse= F∆t
4
Q
Radian
A
a unit of angle measurement, equivalent to 180/pi
5
Q
Angular displacement
A
vector measurement of the angle of which something has moved
angular displacement=s/r
6
Q
Centripetal acceleration
A
the acceleration towards the center of a circle that corresponds to the changes in the direction to maintain an object’s motion around that circle
a=rw^2=v^2/r
7
Q
Centripetal force
A
the resultant force towards the center of the circle to maintain an object’s circular motion
F=mrw^2=mv^2/r
