Force Flashcards
What is Force?
A push or pull exerted on an object in order to change the motion of the object.
What is Motion?
A change in position over time.
What is Net Force?
The combination of all the forces acting on an object.
What is Speed?
Distance traveled per rate of time.
Speed= distance/time.
What is Velocity?
The speed and direction of an object.
What is Acceleration?
The rate at which velocity changes over time.
What is Newton’s First Law?
An object at rest will remain at rest and an object in motion unless acted upon by an outside force.
What is Newton’s Second Law?
Force = mass x acceleration.
What is Newton’s Third Law?
For every action there is an equal but opposite reaction.
What is Inertia?
The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object.
What is Friction?
A force that resists motion.
What is Mass?
The direction of matter in an object.
What is Gravity?
An attractive force that exists between all objects that have mass.
