Newton's third law of motion states that for every action, there is an equal and opposite reaction.
Newton's second law of motion describes how the velocity of an object changes when it is subjected to an external force.
Forces 
A push or pull that can cause an object to change its motion.
Newton 
The unit of force, measured in Newtons (N).
Displacement 
A change in an object's position.
Speed 
The rate of change of distance.
Potential Energy 
Energy stored due to an object's position or shape.
Simple Machines 
Type of machines that use mechanical advantage to simplify tasks.
Friction 
A force that resists motion between two surfaces in contact.
Inertia 
The tendency of an object to resist changes in its motion. Applies to both stationary and moving objects.
Opposite Forces 
Forces that act in opposite directions, resulting in no net force. Examples include frictional forces and reaction forces.
Action-Reaction Pairs 
When an object applies a force, it sends an equal and opposite force back to the object. Examples include traction, friction, and thrust.
Gravity 
The force that attracts two objects with mass towards each other. The strength of the force depends on the mass of the objects and the distance between them.
