Force Basics
This is the term for a push or a pull in physical science.
What is a force?
The law that explains a rocket lifting off is this numbered Newton law.
What is Newton's third law?
Speed is calculated by dividing this by time.
What is distance?
This force occurs when two surfaces rub against each other.
What is friction?
When two forces act in the same direction, this happens to their strength.
What is they add together?
Balanced forces acting on an object never cause this.
What is a change in motion?
If you know how far an object travels and how long it took, you can determine this property of the object.
What is speed?
This type of friction occurs when bike tires roll on the road.
What is rolling friction?
The tendency of an object to resist changes in motion is called this.
What is inertia?
Newton’s second law relates force to mass and this property of motion.
What is acceleration?
The term for the rate of change in an object’s velocity.
What is acceleration?
Air resistance is an example of this category of forces.
