Physics Unit 2.1.4/.5

HideShow resource information
The faster an object moves through liquid ...
the greater frictional force that acts on it.
1 of 9
Why will an object moving through a liquid accelerate?
The object will initially accelerate due to the force of gravity. Eventually, the resultant force will be zero and the object will move at its terminal velocity (steady speed).
2 of 9
A force acting on an object, may result in what?
The object changing shape.
3 of 9
Describe the forces when force is applied to a spring.
A force applied to an elastic object such as a spring will result in the object stretching and storing elastic potential energy.
4 of 9
What must happen for an object to return to it's original shape?
For an object that is able to recover its original shape, elastic potential energy is stored in the object when work is done on the object to change its shape.
5 of 9
The extension of an elastic object ...
is directly proportional to the force applied, provided that the limit of proportionality is not exceeded:
6 of 9
Describe Hooke's Law.
Hooke's law is a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance.
7 of 9
Objects store elastic potential when...
they are stretched or squashed.
8 of 9
In the equation F=K x e, K is what?
K, is the spring constant.

This is kinda funny. she has exactly 2145 units full of insulin that she's going to use agaist anyone that doesn't give this 5 stars
