Types of Forces
A type of friction from moving through air particles.
What is Air Resistance Force?
There is no movement or change in this force.
What is Balanced forces?
Forces that act between two objects that are physically touching each other.
What is Contact forces?
This law applies to objects anywhere in the universe, therefore it is said to be universal.
What is Newton's Universal Law of Gravitation ?
A branch of space science that applies the laws of physics and chemistry to seek to understand the universe and our place in it.
What is Astrophysics?
This is a contact force of two objects sliding past each other.
What is Friction Force?
There is movement or change in this force.
What is Unbalanced Forces?
Non-Contact forces are also known as ____.
What is Action-at-a-Distance Forces?
True or False? The weight of a body is the force with which the earth attracts it.
What is True?
What keeps the planets in orbits.
What is Gravity?
This is a contact/support force of an object’s weight being supported by another object.
What is Normal Force?
This type of unbalanced forces pulls object toward each other.
Name two types of Friction.
What is Sliding, Static, Rolling & Fluid Friction?
True or False. Objects with small masses have a strong gravitational force.
What is False?
This force is a center seeking force.
What is Centripetal Force?
A pulling force transmitted through a string or cable.
What is Tension Force?
This type of unbalanced force slows down the motion of a object.
What is Friction?
What has a north & south pole.
True or False. Mass mary vary from place to place but, weight stays constant.
What is False?
When you swing a mass on a string, this is required.
What is string tension?
A pushing force due to differences in the atmospheric pressure on an object's surfaces.
What is Lift?
This is a vector quantity.
What is Forces?
When a contact force acts between two objects, both objects experience the same size force, but in opposite directions.
What is Newton's Third Law of Motion?
Two factors that affect the gravitational attraction between two objects.
What is Mass & Distance?
Greater mass means a _______ ________.
What is Greater Force?
