What prevents the diver from moving in a straight line once she jumps from the platform?
After the diver jumps forward from the diving board, the force of gravity will accelerate the diver parallel to the direction of motion. body can stop it about five times faster than the pull of gravity that accelerated it. – 10.
What does Newton’s second law of motion state?
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. Newton’s second law is one of the most important in all of physics.
What is the outward force from a surface?
Normal force. The outward force from a surface.
What is the reaction force of a flying bird?
A bird flies by use of its wings. The wings of a bird push air downwards. In turn, the air reacts by pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air (downwards) is opposite the direction of the force on the bird (upwards).
Is centrifugal force related to gravity?
Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis. Thus it is opposite to the direction of gravity at the equator; at Earth’s poles it is zero.
What happens when a diver reaches the water?
Once diver reaches the water, we see water splashing and hear noise of splash. Thereafter the diver comes to rest. Now his potential energy becomes zero. And converted kinetic energy has been converted in to kinetic energy, heat energy and sound energy of water.
How to calculate the velocity of a diver?
A diver leaves the end of a 4.0 m high diving board and strikes the water 1.3s later, 3.0m beyond the end of the board. Considering the diver as a particle, determine: the magnitude of her initial velocity, My workings. horizontal => $v_x=d/t=3.0m/1.3m = 2.31$ vertical => $ S = S_0 + V_v t + 1/2at^2 $ $ 0 = 4m + V_v1.3 -4.915(1.3)^2$
Which is true about the force of water?
True True or False ; when the driver hits the water the force of the water against hurt body can stop it about five times faster than the pull of gravity that accelerated it False True or false; If a diver doesn’t have the correct form when she enters the water, the force of the water can accelerate her speed False
What happens when a diver jumps off a springboard?
While standing on the diving board his velocity is zero. As such kinetic energy is also zero. Once he jumps off the springboard we see he gets additional energy from the springboard and falls down under action of gravity #g#.
