Final answer:
Newton's second law of motion is evident in our daily lives when kicking a ball, braking a car, dropping objects of different mass like a feather and a rock, weightlifting, and pulling a grocery cart. In all these cases, the relationships between force, mass, and acceleration are shown.
Step-by-step explanation:
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Here are five examples of this law in our day-to-day life:
- Kicking a Ball: When you kick a ball, it undergoes acceleration (movement). The harder you kick (more force), the faster the ball moves (greater acceleration). This is a direct representation of Newton's second law.
- Car Braking: When brakes are applied to a moving car, a force is exerted opposite to the direction of the car's motion, causing it to slow down or accelerate negatively.
- Feather and a Rock: If you drop a feather and a rock from the same height, the heavier rock falls more quickly because the same gravitational force acts on both, but the feather, being lighter, is more affected by air resistance.
- Weightlifting: When lifting weights, more force is needed to lift heavier weights. This demonstrates the relationship between force, mass, and acceleration.
- Pulling a Grocery Cart: It is easier to push or pull an empty grocery cart than a full one. A greater mass (the full grocery cart) requires a larger force to achieve the same acceleration as a smaller mass (the empty cart).
