Flashcards in Science Deck (10):
the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.
strength or energy as an attribute of physical action or movement.
the speed of something in a given direction
the rate of change of velocity per unit of time.
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
Air resistance is the frictional force air exerts against a moving object. As an object moves, air resistance slows it down. The faster the object's motion, the greater the air resistance exerted against it.
the number of seconds during which a punted ball is in the air.
Along with ball speed, launch angle is a primary component to determining the height and distance of a shot. Every golfer should be fitted to achieve the optimal balance of launch angle and spin rate based on their club speed and ball speed.Oct 30, 2016
And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible). A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
