Matter Matters
To be classified as matter, an object must possess mass and this second specific property.
What is volume?
Morning dew forming on the grass is a real-world example of this phase change.
What is condensation?
Boiling water to make steam is classified as this type of change.
What is a physical change?
Calculate the volume of a wooden cube with sides of 3 cm using V = L x W x H.
What is 27 cm³?
Unlike contact forces, field forces like magnetism can act without requiring this.
What is physical touch?
This standard SI unit is used to measure mass.
What is a kilogram (kg)?
This phase change occurs when a substance transitions directly from a solid into a gas.
What is sublimation?
A metal nail rusting outside undergoes this type of change.
What is a chemical change?
Convert 2.5 kilograms into grams
What is 2,500 grams?
his is defined as an object's resistance to changes in its motion, which increases with mass
What is inertia?
Light and heat are usually not classified as matter because they lack volume and mass but are they classified as...
What is energy?
To turn a liquid into a solid, this thermal energy must be removed to slow down particle motion.
What is heat (or thermal energy)?
Unlike physical changes, chemical changes alter chemical identity to form new ones of these.
What are substances (or molecules)?
Calculate the density of a sample with a mass of 105 g and a volume of 10 cm³
What is 10.5 g/cm³?
This specific support force always acts perpendicularly to a surface to hold an object up
What is the normal force?
This is the correct formula used to calculate density.
What is Density = Mass / Volume (D = m/v)?
According to particle dynamics, if temperature drops to absolute zero, this action stops entirely.
What is particle movement?
Burning wood leaves a small pile of ash because missing mass escapes as gas under this law.
What is the Law of Conservation of Mass?
Using W = m x g (where g = 9.8 m/s²), calculate the weight in Newtons of a 12 kg dog on Earth
What is 117.6 N?
Newton's Third Law states that for every action, there is an equal and opposite this
What is a reaction?
This property of an object stays completely identical whether measured on Earth or on the Moon.
What is mass?
List all of matter phase changes.
A physical change typically has this characteristic regarding undoing the process.
What is reversible?
Using F = ma, calculate the net force of a 1,200 kg sports car accelerating at 4.5 m/s²
What is 5,400 N?
According to Newton's First Law, what is the net force acting on an object at rest or at constant velocity?
What is zero?
