Science 3.1-3.7 Flashcards
A change in position
Motion
The push or pull on an object
Force
Movement resulting from force
Work
A force that works against motion along a surface
Friction
Opposing forces that prevent work from being done
Balanced forces
A greater force that overcomes opposing forces, resulting in work
Unbalanced forces
What are forces we experience everyday?
Friction, gravity, weight and magnetism
Newton’s discoveries about how motion always works
Laws of motion
The property of matter that makes it resist change in motion
Inertia
What is the first rule of inertia?
An object at rest will stay at rest unless acted upon by an unbalanced force
What is the second rule of inertia?
An object in motion will move in a straight line at a constant speed unless acted upon by an unbalanced force
Two objects bumping into each other, causing energy transfers
Collision
What are parts of an objects moving energy?
Mass, speed and direction
The attracting and repelling force created by a magnetic field
Magnetism
Having two opposite sides that work differently
Polarity
