Forces and Friction
Equal forces acting on an object in opposite direction. No motion, object not in motion.
What is Balanced Forces?
This law explains the motion of an object using the mathematical formula: Force (N) = mass x acceleration.
What is Newton's Second Law of Motion?
The distance that an object travels over a unit of time.
What is Speed?
SI for short - known as the metric system of measurement.
What is International System of Units?
The basic SI unit for length.
What is Meter?
Force that produces motion or causes an object to move or change the direction of the object's motion. Nonzero net force!
What is Unbalanced Force?
Newton's First Law of Motion is also known as...
What is Inertia?
This occurs when two objects move over each other and come into contact with each other. Example: sand on icy road.
What is Sliding Friction?
A place, point or object used as a reference to help the observer determine if an object is in motion.
What is Reference Point?
The speed of an object at one instant of time.
What is Instantaneous Speed?
When a body or object is forced to move along another surface but the body or object is not moving.
What is Static Friction?
For every action there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
The overall rate of speed which an object travels over a distance and the direction that the object is moving. Speed with a ______.
What is Average Velocity?
This term describes how far an object moves from its original starting point. Considered to be a vector quantity.
What is Displacement?
The state of one object's distance in relation to another object. When objects get closer or further apart.
What is Motion?
A force that slows down a rolling object's motion.
What is Rolling Friction?
This occurs when an object speeds up, slows down or changes direction or velocity.
What is Acceleration?
The product of an object's mass and velocity.
What is Momentum?
The overall rate of speed which an object travels over a distance. Calculated by the formula. Speed = Distance/Time.
What is Average Speed?
Occurs when two objects slide over each other. Example: sand on an icy sidewalk to improve footing, rubber brake
pads rubbing on tire rim to slow a bike.
What is Sliding Friction
A push or pull on an object. Ex: Gravity
What is Force?
A body or object at rest remains at rest unless acted on by another force. A body or object in motion tends to remain in motion until acted on by another force.
What is Newton's First Law of Motion.
Force that pulls all objects towards each other. Example: Earth's attraction to the Sun.
What is Gravity?
Determines if an object moves and in which direction.
What is Net Force?
The amount of space or length between two points or objects. Measured in meters, centimeters, millimeters, kilometers!
What is Distance?
