• Motion occurs everywhere around us and is the change in position of an object with respect to its surroundings in a given interval of time.
• Equilibrium is a state in which opposing forces or influences are balanced, and an object in static equilibrium has no acceleration in any direction.
• An object in equilibrium will continue in that condition indefinitely unless disturbed by an outside force.
• Aristotle identified two main types of motion: Natural, which occurs naturally and is caused by a gravitational force, and Violent, which occurs because something has caused it to move and is caused by a natural phenomenon such as an earthquake.
• Galileo Galilei stated that an object will continue to move with constant velocity if no external force acts on it to affect its motion.
• Sir Isaac Newton stated that Force and Motion are involved, and Force is the push or pull by one body to another that causes an object to move or remain in motion.
• Balanced Forces refer to forces that are equal and acting on an object in opposite directions, resulting in no acceleration and the object staying still.
• Unbalanced Forces refer to forces that cause a change in the motion of the object, occur when two forces acting in opposite directions on a body are not equal in magnitude and size, and result in acceleration.
• Newton’s Laws of Motion explain the relationship between motion and force, with the First Law stating that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by a net external force.
• The Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the object's mass, quantified in the equation F=ma.
• The Third Law of Motion states that for every action, there is an equal and opposite reaction, meaning when an object exerts a force on a second object, the second object exerts an equal force in the opposite direction.
• Friction is a resistive force that slows things down and stops objects sliding past each other, acting in the opposite direction to which the object is moving or trying to move.
• Motion occurs everywhere around us and is the change in position of an object with respect to its surroundings in a given interval of time.
• Equilibrium is a state in which opposing forces or influences are balanced, and an object in static equilibrium has no acceleration in any direction.
• An object in equilibrium if it experiences neither linear acceleration nor angular acceleration, unless it is disturbed by an outside force, it will continue in that condition indefinitely.

• Balanced Forces refer to forces that are equal and acting on an object in opposite directions, resulting in no acceleration, the object stays still.
• Unbalanced Forces refer to forces that cause a change in the motion of the object, there is a "greater force" acting on an object, and it occurs when two forces acting in opposite directions on a body are not equal in magnitude and size, resulting in acceleration.
• Newton's Laws of Motion explain the relationship between motion and force, including the First Law of Motion: An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by a net external force.
• The Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the object's mass, this law quantifies how the velocity of an object changes when subjected to an external force.
• The Third Law of Motion states that for every action, there is an equal and opposite reaction, when an object exerts a force on a second object, the second object exerts an equal force in the opposite direction.
• Friction is a resistive force that slows things down and stops objects sliding past each other, it acts in the opposite direction to which the object is moving or trying to move.
