What is a force? - A force is a push or a pull., What three things can an unbalanced force change about an object? - Speed; Direction; Shape, What are the characteristics of balanced forces? - Forces are equal in size but opposite in direction, What happens to an object when the forces acting on it are balanced? - It remains at rest or continues at the same speed and in the same direction., What are the characteristics of unbalanced forces? - Forces are not equal in size, which changes an object's motion, What happens to an object when the forces acting on it are unbalanced? - The object will accelerate, decelerate, or change shape., What is the unit of measurement for force? - Newtons (N), What is Newton's first law of motion? - An object at rest stays at rest, and an object in motion continues moving at a constant velocity unless acted upon by an unbalanced force., What is Newton's second law of motion? - The acceleration of an object is directly proportional to the unbalanced force acting on it and inversely proportional to its mass, expressed as F=ma, What is Newton's third law of motion? - Every action force has an equal and opposite reaction force.,
