1

Hooke's Law

States that the extension of a material is directly proportional to the force applied.

New cards
2

Deformation

The change in shape or size of a material due to the application of forces.

New cards
3

Opposite Forces

A pair of forces acting in opposite directions on an object, leading to deformation.

New cards
4

Robert Hooke

A scientist who discovered Hooke's Law in the 17th century.

New cards
5

Force Constant

Denoted as k, it represents the stiffness of an object being stretched and is measured in Nm¯¹.

New cards
6

Hooke's Law

States that the extension or compression of a spring is directly proportional to the force applied.

New cards
7

Spring Stiffness

Denoted by k in the formula △F = k△x, it represents the spring constant or how stiff the spring is.

New cards
8

Tensile Forces

Forces that act to stretch an object, such as a spring, in opposite directions.

New cards
9

Compressive Forces

Forces that act to compress or squash an object, like a spring, from opposite directions.

New cards
10

Material Compliance

Most materials, not just metal springs, exhibit behavior that follows Hooke's law up to a certain point.

New cards
11

Hooke's Law

States that the extension of a material is directly proportional to the force applied.

New cards
12

Elastic Limit

The point on a force-extension graph beyond which the material will be permanently deformed.

New cards
13

Stiffness Constant (Force Constant)

Denoted by k, it represents the stiffness of the object being stretched in Hooke's Law.

New cards
14

Limit of Proportionality

The point on a force-extension graph where Hooke's Law ceases to be valid.

New cards
15

Graph of Force against Extension

Illustrates the relationship between force and extension for a material, showing Hooke's Law followed by a curved region beyond the elastic limit.

New cards
16

Elastic Deformation

Deformation that is reversible, where the material returns to its original shape once the forces are removed.

New cards
17

Plastic Deformation

Deformation that is irreversible, causing the material to be permanently stretched.

New cards
18

Tensile Deformation

Deformation due to tension, where atoms are pulled apart from one another.

New cards
19

Compressive Deformation

Deformation due to compression, where atoms move position relative to one another.

New cards
20

Elastic Limit

The point up to which a material shows elastic deformation before undergoing plastic deformation.

New cards
21

Investigating Extension

Process of conducting an experiment to measure the change in length of an object when weights are added to it.

New cards
22

Extension

The change in length of an object, calculated as the difference between the new length and the original (natural) length.

New cards
23

Hooke's Law

A principle stating that the force needed to extend or compress a spring by a certain distance is proportional to that distance.

New cards
24

Fiducial Marker

A thin tag on the object that marks the point where measurements are taken to ensure accuracy.

New cards
25

Line of Best Fit

A straight line drawn on a graph that best represents the relationship between the variables being studied.

New cards
26

Interpolation

Estimating a value within the range of known values based on the existing data points.

New cards
27

Safety Goggles

Protective eyewear worn during experiments to prevent eye injuries from potential hazards.
