Physics 1

• What is an elastic material?

  An elastic material returns to its original shape after the forces of bending and stretching are removed.
• How does a plastic material behave when forces are applied?

  A plastic material maintains its new shape after the forces of bending and stretching are removed.
• What does the extension of a spring refer to?

  The extension of a spring is equal to the change in length when forces are applied.
• What happens to the extension of a spring when the force applied is doubled?

  The spring's extension doubles when the force applied is doubled.
• What does the line that strikes the origin represent in relation to spring extension?

  The line that strikes the origin indicates that the extension is directly proportional to the force applied.
• What is the spring constant equation?

  • The equation is given by: $F =$$k \cdot x$
  • Where:
  • $F$ = Force (N)
  • $k$ = Spring constant (N/m)
  • $x$ = Spring extension (m)
• What are the units for spring constant?

  The units for spring constant are Newtons per meter (N/m).
• What is the unit of force in the spring constant equation?

  The unit of force in the spring constant equation is Newtons (N).
• What is the unit of spring extension in the spring constant equation?

  The unit of spring extension in the spring constant equation is meters (m).
• What is the elastic limit in relation to the limit of proportionality?

  The elastic limit is always at or beyond the limit of proportionality.
• What is the equation for energy transferred in stretching a spring?

  E = \frac{1}{2} K x^2
• What does the variable E represent in the energy transferred equation?

  E represents the energy transferred in stretching.
• What does the variable K represent in the energy transferred equation?

  K represents the spring constant measured in N/m.
• What does the variable x represent in the energy transferred equation?

  x represents the spring extension in meters.
• What is the unit of the spring constant K?

  N/m (Newtons per meter)
• How is the spring extension x represented in the energy transferred equation?

  x is squared in the equation, represented as x².
• What is the formula for spring extension in the energy transferred equation?

  x² = spring extension (m²)
• What does the equation E = \frac{1}{2} K x^2 imply about the relationship between energy transferred and spring extension?

  The energy transferred increases with the square of the spring extension.
• How does the elastic limit relate to the behavior of materials under stress?

  The elastic limit indicates the maximum stress a material can withstand without permanent deformation.
