Assertion: When same force is applied for same time, to both car and truck. The car picks upa greater speed than truck in that time.Reason: The magnitude of force needed depends on the mass of object and value of change ofa greater speed than truck in that time
Question
Assertion: When same force is applied for same time, to both car and truck. The car picks upa greater speed than truck in that time.Reason: The magnitude of force needed depends on the mass of object and value of change ofa greater speed than truck in that time
Solution
The assertion and reason are correct and they are related. The assertion is based on Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
So, when the same force is applied to both a car and a truck for the same amount of time, the car, being lighter, will pick up a greater speed than the truck. This is because the force has a greater effect on the lighter car than on the heavier truck.
The reason is also correct because the magnitude of force needed to change an object's motion does indeed depend on the mass of the object. The heavier the object, the more force is needed to change its motion. Therefore, a truck, being heavier than a car, requires more force to achieve the same change in speed.
