Newton’s first law
Newton’s First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Balanced Force
Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.
Unbalanced force
When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
Inertia
a tendency to do nothing or to remain unchanged.
Gravity
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton’s laws of gravity apply, with minor modifications to take the general theory of relativity into accoun
Gravitational pull
Definition of the Earth’s Gravitational Pull. The gravitational pull of the earth is the attraction that the earth exerts on an object or that an object exerts on the earth.
Orbit
the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution.
Rotation
the action of rotating around an axis or center.
Revolution
an instance of revolving.
Electro magnet
a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
Static electricity
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
Proximity
nearness in space, time, or relationship.
Newton’s second law
Newton’s second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Newtons third law
Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
