What is the density equation?

density = mass / volume

What is the volume equation for a cube?

volume = length^3

What is the particle arrangement and movement in a solid?

Particles are in a regular structure and vibrate in fixed positions.

What is the particle arrangement and movement in a liquid?

Particles are in a random arrangement and free to move/flow past each other.

What is the particle arrangement and movement in a gas?

Particles are in a random arrangement and move rapidly in random directions.

What happens to particle kinetic energy when temperature increases?

Kinetic energy increases causing particles to move faster.

What happens to gas pressure inside a rigid container when heated?

Pressure increases because particles collide with container walls more frequently and with more force.

What is the definition of gas pressure?

Gas pressure is the total force exerted by particle collisions per unit area on the container walls.

What term describes energy spreading out to the surroundings?

Dissipated

Calculate the density of a metal cube with mass 0.432 kg and side length 0.04 m.

Formula: density = mass / volume, Substitution: 0.432 / 0.04^3, Evaluation: 6750 kg/m^3

Calculate the density of a copper cube with mass 0.064 kg and side length 0.02 m.

Formula: density = mass / volume, Substitution: 0.064 / 0.02^3, Evaluation: 8000 kg/m^3

What is Newton's Second Law equation linking force mass and acceleration?

force = mass x acceleration (F = ma)

Calculate the acceleration of a 1200 kg car with a forward driving force of 4500 N and resistive force of 900 N.

Formula: a = (driving force - resistive force) / mass, Substitution: (4500 - 900) / 1200, Evaluation: 3 m/s^2

What is the equation for work done?

work done = force x distance (W = Fs)

Calculate the work done when a force of 250 N moves an object through a distance of 8 m.

Formula: W = F x s, Substitution: 250 x 8, Evaluation: 2000 J

What is Hooke's Law equation?

force = spring constant x extension (F = ke)

How do you calculate extension from original length and stretched length?

extension = stretched length - original length
