Newton's Laws
This law states that an object in motion stays in motion unless acted on by an outside force.
What is Newton’s First Law?
This law states that momentum remains constant in a system without external forces.
What is the Law of Conservation of Momentum?
This measurement reflects the average kinetic energy of molecules.
What is temperature?
Heat transfer by electromagnetic waves.
What is radiation?
Whether an object floats depends on the relative values of these two densities.
What are the densities of the object and the fluid?
This formula expresses Newton’s Second Law: Force equals mass times acceleration.
What is F = ma?
Doubling an object’s speed increases its kinetic energy by this factor.
What is four (quadruples)?
He created the first “thermal meter.
Who is Galileo?
Heat transfer through direct contact.
What is conduction?
Surface tension is caused by this force between molecules.
What is molecular attraction?
This property describes an object’s tendency to resist changes in motion.
What is inertia?
Energy that depends on mass, height, and gravity is known as this.
What is gravitational potential energy?
This temperature scale is the absolute scientific scale.
What is Kelvin?
During any phase change, temperature does this.
What is remains constant?
Gaps in railroad tracks exist for this reason.
What is thermal expansion?
This law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third Law?
This term is defined as force multiplied by time.
: This term is defined as force multiplied by time.
At this temperature, molecular motion stops.
What is absolute zero?
This describes the energy needed to turn a solid into a liquid.
What is the latent heat of fusion?
These joints allow buildings to move with temperature changes.
What are expansion joints?
In a collision where one billiard ball stops and the other moves away with equal speed, the collision is this type.
What is an elastic collision?
Energy cannot be created or destroyed, only transformed.
Energy cannot be created or destroyed, only transformed.
Water uniquely does this when it freezes.
What is expand?
Fog forms due to this phase change.
What is condensation?
The triple point of water is when water exists as these three phases at once.
What are solid, liquid, and vapor?
