A car traveling 75 miles per hour describes this quantity of motion.
What is speed?
This law explains why passengers fly forward when a car suddenly stops.
What is Newton’s First Law?
Heat transfer that occurs through direct contact.
What is conduction?
This force keeps planets moving in their continuous orbits around the Sun.
What is gravity?
As temperature increases, this happens to particle motion.
What is increases?
A car traveling 75 miles per hour north describes this quantity of motion.
What is velocity?
A sheet of paper stays motionless on a table because of this type of force.
What are balanced forces?
Heat transfer that happens when warm fluids rise and cool fluids sink.
What is convection?
Objects in the Kuiper Belt are mostly made of this substance.
What is ice?
This form of energy is absorbed when water changes from liquid to vapor.
What is thermal energy?
An object moving in a circle at constant speed still experiences a changing form of motion.
What is velocity?
These forces can stop a soccer ball from continuing to roll.
What are gravity and friction?
The Sun warming Earth's surface is this type of thermal transfer.
What is radiation?
Mars travels in a curved orbit around the Sun because of this force acting between them.
What is gravity?
An ice cube melts in a warm room because heat does this.
What is it moves into the ice cube?
This pair of examples represents speed or velocity: 20 m/s north and 10 km/h southeast.
What are examples of velocity?
Earth’s revolution around the Sun occurs because this type of force continually changes its direction.
What is an unbalanced force?
When molecules gain kinetic energy, they move faster and this quantity increases.
What is temperature?
According to the mass of planets, this planet has the strongest gravitational force.
What is Jupiter?
Thermal energy flows from high temperature to low temperature and from high kinetic energy to low kinetic energy.
What is heat transfer?
A flat line on a distance-time graph indicates this condition.
What is the object is not moving?
This force keeps objects moving in curved orbital paths instead of in straight lines.
What is gravity?
Mammals can warm themselves because they obtain energy for heat from this source.
What is food?
Both the Moon’s orbit around Earth and Earth’s orbit around the Sun are caused by these two factors interacting.
What are gravity and inertia?
As water in a pot heats up, this happens to the speed of its molecules.
What is they move faster?
