Force and Motion Flashcards
to understand the concepts
Motion
the process of changing position
Reference Point
the starting point you use to describe the motion or position of an object.
Distance
The total length of your path.
Displacement
Distance between starting point and final position
Speed
The distance an object moves divided by the time it took to move that distance.
Velocity
Speed and direction of an object’s motion
Acceleration
the measure of the change in velocity during a period of time.
Force
the push or pull on an object
Contact Force
Contact Force
the push or pull applied by one object to another object that is touching it.
Non Contact force
A force that pushes or pulls an object without touching it.
Friction
a contact force that resists the sliding motion between two objects that are touching.
Gravity
A non contact attractive force that exists between all objects that have mass.
Balanced Forces
When the net force on an object is 0 N.
Unbalanced Forces
When the net force on an object is not 0 N.
Inertia
the tendency of an object to resist a change in motion.
