Final answer:
Examples of forces and motion observed in the video include objects accelerating in the direction of applied force, objects in equilibrium with balanced forces, and circular motion with centripetal forces.
Step-by-step explanation:
In the video, examples of forces and motion can be observed. One example is when an object is pushed and it accelerates in the direction of the force applied. This demonstrates Newton's second law, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
Another example is when an object is in equilibrium, with the forces acting on it balanced. This is illustrated by an object hanging from a string, where the gravitational force pulling downwards is balanced by the tension force pulling upwards. This demonstrates Newton's first law, which states that an object will remain at rest or move with constant velocity in a straight line if the net force acting on it is zero.
Additionally, the video shows examples of circular motion, where objects move in a curved path. Circular motion requires a centripetal force directed towards the center of the circle to keep the object moving in the curved path. This demonstrates Newton's laws of motion applied to circular motion.
