Forces and Elasticity

Question 1

Elastic objects store energy as [ ]

Answer 1

Elastic potential energy

Question 2

What is an elastic object?

Answer 2

An object that can return to its original shape after it has been stretched/changed shape

Question 3

[ ] to an elastic object to change its shape. The energy is stored as [ ]

Answer 3

Work is done

elastic potential energy

Question 4

The elastic potential energy is then converted to [ ] when the force is removed and the object [ ]

Answer 4

kinetic energy

returns to its original shape

Question 5

What is the equation for force applied on a string?

Answer 5

F = k*e
Force (N)
k = Spring constant (N/m)
e = extension (m)

Question 6

There’s a maximum force that the elastic object can take and still extend [ ]. This is know as the [ ]. If you increase the force past this then the material will be [ ]

Answer 6

proportionally
limit of proportionality
permanently stretched
