an English scientist and
mathematician famous for
his discovery of the law of
gravity also discovered the
three laws of motion. correct answers Sir Isaac Newton (1643-1727)
Newton's Laws of Motion correct answers 1. An object in motion tends to stay in motion and
an object at rest tends to stay at rest unless acted
upon by an unbalanced force.
2. Force equals mass times acceleration
(F = ma).
3. For every action there is an equal and opposite reaction.
An object at rest tends to stay at rest and an object in
motion tends to stay in motion unless acted upon by an
unbalanced force. correct answers Newton's First Law
an object will "keep doing what
it was doing" unless acted on by an
unbalanced force. correct answers Newton's First Law
If the object was sitting still, it will remain
stationary. If it was moving at a
constant velocity, it will keep moving. correct answers Newton's First Law
It takes force to change the motion of an
object. correct answers Newton's First Law
If the forces on an object are equal and opposite, they are said
to be balanced, and the object experiences no change in
motion. If they are not equal and opposite, then the forces are
unbalanced and the motion of the object changes. correct answers unbalanced
force
A soccer ball is sitting at rest. correct answers Newton's First Law
Newton's First Law is also called correct answers the Law of Inertia
states that all objects have inertia. The
more mass an object has, the more inertia it has (and
