magnitude
balanced forces
unbalanced force
force
Sir Isaac Newton
Newton's 1st Law
The magnitude, or strength, of the forces are the same, resulting in NO change in motion or velocity.
Balanced Forces
a push or pull between two objects
Force
an act, process, or instance of changing position or location
Motion
The magnitude, or strength, of the forces are not the same, resulting in a change in motion or velocity.
Unbalanced Forces
The tendency of an object to remain stationary or remain in motion.
Inertia
Isaac Newton was born in 1643 and became famous for his work on gravity and his three laws of motion. He was also well known for his work on light and colour.
Sir Isaac Newton
The strength, size, or extent of something.
Magnitude
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
