Was Hooke's Law valid for your simulation?

Yes - the graph of displacement/force was a straight line.

No - the graph goes below the x axis and is therefore not valid.

Yes, because Hooke's law is always true.

No - the gradient was not equal to the stiffness.

Which of the following statements is true about Hooke's law as it applies to springs?

Hooke's law is true for all springs, in all circumstances.

Hooke's law is true for some springs, and only for small deviations from the equilibrium position.

Hooke's law is true but only for stretching springs; it is not valid for compression.

Hooke's law is true for some springs, and only for large deviations from the equilibrium position.

Imagine an elastic collision between two objects of different masses:

Which of the following equations can be used to describe the relationship between the variables before and after the collision?

Note here that the diagram is not necessarily to scale.

Imagine a perfectly inelastic collision between two objects of different masses:

Which of the following equations can be used to describe the relationship between the variables before and after the collision?

Imagine an inelastic collision between two objects of different masses:

Which of the following equations can be used to describe the relationship between the variables before and after the collision?

Which of the following matches the definition of an inelastic collision? Note that this is NOT the same thing as a perfectly inelastic collision.

An inelastic collision is one in where the total momentum is conserved.

An inelastic collision is one where the two objects have the same final velocity - this is the minimum kinetic energy condition.

An inelastic collision is one where the total kinetic energy is not conserved, but the final kinetic energy is above the minimum possible value.

An inelastic collision is one in where the total momentum is not conserved, but the final momentum is above the minimum possible value.

Which of the following best matches the description of a perfectly inelastic collision?

A perfectly inelastic collision is one for which the kinetic energy after the collision is not conserved, but is above the minimum possible value.

A perfectly inelastic collision is one for which the kinetic energy after the collision is the minimum possible value.

A perfectly inelastic collision is one for which the momentum after the collision is the minimum possible value.

A perfectly inelastic collision is one for which momentum is conserved.
