1) Inertia is the tendency of an object to resist changes in its motion. Mass, on the other hand, is the measure of the amount of matter an object contains. The relationship between inertia and mass is that the more mass an object has, the more inertia it will have. In simpler terms, objects with larger masses are more resistant to changes in their motion.
2) According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When a jellyfish squeezes its body, it pushes a stream of water out of its back end. As a result, according to Newton's third law, there will be an equal and opposite reaction force exerted on the jellyfish in the opposite direction. This will propel the jellyfish forward, aiding in its movement.
3) Momentum is a property of moving objects and is calculated as the product of an object's mass and its velocity. To compare momentum, we multiply the mass and velocity of each option. The one with less momentum than a 52 kg cheetah running at 10 m/s is the option that results in the smallest product of mass and velocity. In this case, it is option C, a 5,000 kg elephant walking at 1 m/s. To find the momentum, multiply the mass (5,000 kg) by the velocity (1 m/s).
4) According to Newton's third law of motion, the force exerted by the wall on the ball will be equal in magnitude but opposite in direction to the force exerted by the ball on the wall. Since the ball exerts a force of 3 N on the wall, the wall will exert a force of 3 N back on the ball.
5) When two cars collide, the total momentum of the system is conserved, as long as there are no external forces acting on the system. This means that the sum of the momenta of the two cars before the collision should be equal to the sum of the momenta after the collision. However, if there are external forces involved, such as friction or an external impact, the total momentum of the system may not be conserved. In such cases, the outside force can change the overall momentum of the collision.
