A force is a push or pull that can change an object's motion, while balance will not change it. Inertia is the tendency of an object to resist changes in its state of motion. The net force is the vector sum of all forces and can alter an object's motion.
A force is a push or pull on an object that has both magnitude and direction, making it a vector quantity. This force can affect the motion of objects in various ways, in accordance with Newton's laws of motion. Here are the answers to the fill-in-the-blank questions:
Balance will not change an object's motion.
A net force can change an object's motion.
A force is a push or pull.
Inertia is the tendency to resist a change in motion.
Net force is the sum of all forces acting on an object.
Newton's first law, often referred to as the law of inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net force.
Newton's second law of motion quantifies this change in motion, and Newton's third law reminds us that forces always occur in pairs of equal magnitude and opposite direction.
External forces, such as friction, are forces that act on an object or system from the outside and can have a significant impact on its motion. When the net force on an object is zero, it is in a state of equilibrium and will not accelerate.
