Compass Rose
In order for our results to be accurate, we must use a __________unit of measurement.
Standard
Any motion in which an object is moving along a curved path.
Circular Path
A push or pull on an object.
Force
The amount of matter in an object.
Mass
The starting point you use to describe the location or position of an object.
Reference Point
The _____________ system is used throughout the world. For example meter.
Metric
An object at rest will stay at rest unless an external force acts on it.
Newton's First Law
A force that one object can apply to another object without touching it.
Noncontact Force
The gravitational force exerted on an object.
Weight
The two requirements needed to state a location.
Distance and Direction
What is an educated guess about a phenomenon that can be tested through research and experimentation?
Hypothesis
For every action (force) there is an equal and opposite reaction (force).
Newton's Third Law
The combination of all the forces acting on an object.
Net Forces
A force that resists the motion of two surfaces that are touching.
Friction
Using negative in directions means moving
backwards
The rate at which work is done.
power
The greater the mass of an object, the more force is needed to accelerate that object (speed it up or slow it down).
Newton's Second Law
A push or pull on one object by another that is touching it.
Contact Force
An attraction force that exists between all objects that have mass.
Gravity
The process of changing position is known as
motion
Doing work on an object transfers ___________to that object.
Energy
The greater the mass of an object, the more force is needed to accelerate that object (speed it up or slow it down).
Forces acting on an object that combine and form a net force of zero.
Balanced Force
The tendency of an object to to resist a change in its motion.
Inertia
