The branch of science that studies matter and energy and its motion and interactions and all that is derived from it like force is known as Physics.
the action or process of moving or of changing place or position
attractive force between two objects that depends on the masses of the objects and the distance between them.
is always 90 degrees to contact surface
to push forcibly; shove; put or drive with force
force that opposes the sliding motion between two touching surfaces
is a force acting opposite to the relative motion of any object moving with respect to a surrounding environment (air, water, etc)
tending to float in a fluid
a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet
the act of stretching or straining
to move or bring (something) upward from the ground or other support to a higher position
the speed and direction of a moving object.
distance an object travels per unit of time
usually given the symbol p. Property of a moving object that equals its mass times its velocity.
the act of opposing (air acting upon an airplane creating drag is known as air resistance
resistance of an object to changes in its motion. The greater mass an object has, the greater it will resist changes in motion. Therefore, more massive objects have greater inertia.
Newton's Laws of Motion - First Law
states that an object moving at a constant velocity keeps moving at that velocity (in other words, an object in motion stays in motion) unless an unbalanced force acts on it. It an object is at rest, it stays at rest unless an unbalanced force acts on it. Often referred to as the Law of Inertia
Newton's Laws of Motion - Second Law
states that the acceleration of an object is in the same direction as the net force on an object, and that the acceleration equals the net force divided by the mass.
Newton's Laws of Motion - Third Law
states that for every action force there is an equal and opposite reaction force. In other words, when one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength and opposite in direction.
forces on an object that are equal in size and opposite in direction. Results in a net force of 0 N.
rate of change of velocity; can be calculated by dividing the change in velocity by the time it takes the change to occur.
a push or pull exerted on an object. Measured in Newtons (N)
