u and your family take a road trip on a long holiday weekend. In a certain section of the trip where the road is particularly uneven, the car goes over a bump that is curved downward with a radius of 22.5 m. See diagram below. The mass of the car and its passengers is 1200 kg. (a) When the car is at the highest point of the bump its speed is 7.65 m/s. Determine the magnitude and direction of the force exerted by the road on the car at this highest point. magnitude_______N direction: ( Downward or Upward )( Select One ) (b) If the speed at the highest point is above a certain maximum value the car will lose contact with the road. Calculate this maximum speed. _____m/s
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
