Write True if the statement is correct and False if otherwise. Explain your answer.
1.A motorcycle has more inertia than a bicycle.
2.When you hold your mouse,the force that the mouse exerts on your palm is lesser than the force that your palm exerts on the mouse.
3.The action-reaction happen to two different objects.
4.The second law of motion tells you that you have to exert greater force on objects with greater mass
5.Mass and inertia are the same.
1. False. To determine which object has more inertia, we need to consider their masses. Inertia is the resistance of an object to changes in its state of motion. It is directly proportional to mass. Thus, if a motorcycle has a greater mass than a bicycle, it will have more inertia.
2. False. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you hold your mouse, your palm exerts a force on the mouse. Simultaneously, the mouse exerts an equal force in the opposite direction on your palm.
3. True. Newton's third law of motion states that the action and reaction forces always occur in pairs. However, it is important to note that these forces act on two different objects. For example, if you push a wall, you exert a force (action) on the wall, and the wall pushes back (reaction) on you.
4. False. The second law of motion, also known as Newton's second law, states that force is equal to the mass of an object multiplied by its acceleration. It does not specify that you must exert greater force on objects with greater mass. Instead, it states that to accelerate an object with greater mass, you would need to apply more force.
5. False. Although mass and inertia are related concepts, they are not the same. Mass is a measure of the amount of matter in an object, whereas inertia is an object's resistance to changes in motion. Mass is a scalar quantity, measured in kilograms, while inertia is a property of matter based on its mass. However, the greater the mass, the greater the inertia of an object.
