Lesson: Forces and Newton’s Second Law of MotionPhysics
In this lesson, we will learn how to identify Newton’s second law of motion as the relationship between an object’s mass and its resultant acceleration when a force is applied to it.
Sample Question Videos
A sports car of mass 1,500 kg accelerates from 0 m/s to 30 m/s in a time of 10 s. What average force is exerted on the car during this acceleration?
A car with a mass of 1 000 kg applies brakes when it is moving at 90.0 km/h, and the car comes to rest after travelling 40.0 m. What is the net force on the car during its deceleration?
Find the magnitude of the net force required to bring a car to rest if the mass of the car is 1,050 kg, its initial speed is 40.0 km/h, and its stopping distance is 25.0 m.
