A rock is thrown vertically into the air At the very top of its trajectory the net force on it is?
The net force is gravity. The speed is zero.
What is the definition of fluid force?
The amount of force produced by a fluid.
What is boyant force?
Bouyant Force-is the upward force on a object in a fluid exerted by the surrounding fluid .
What is Turning effect of force?
rotator
What force is the upward force exerted on any object in a fluid?
The upward force exerted on an object in a fluid is buoyancy.
If there was no buoyancy in fluids would everything sink in fluid?
Buoyancy is not a characteristic of fluid but rather it is the upward force on the object that the fluid provides. The only way a fluid could have an effect similar to no buoyancy is if it couldn't provide an upward force great enough to provide the object to stay on top of the fluid.
What force is responsible for a golfball's trajectory?
Gravity and air resistance, after the initial impulse from the club (force x time)
A rock is thrown vertically into the air At the very top of its trajectory the net force on it is?
The net force is gravity. The speed is zero.
What do you mean by elliptical trajectory?
Any planet that orbits a star ( our sun for example ) has an orbital trajectory. This is due to gravity and the centripetal force. An elliptical trajectory is when that planet orbits the star in an ellipse rather than a circle. Ellipse = squashed circle.
What is the name of the force that pulls a capsule out of its straight trajectory and toward the center of the moon?
Gravity.
What type of lever is operating when an athlete throws a javelin?
Third Class Lever. Javelin is the resistance, Shoulder is the axis and Muscles surrounding the shoulder and bicep is the force
What is the definition of fluid force?
The amount of force produced by a fluid.
Is there an optimal angle to throw a javelin?
Throwing a javelin at the optimal angle. Throwing a javeline at the optimal angle is throwing a javelin at the angle which the air flows efficiently around the javeline.The center of pressure is the aerodynamic force of drag and lift on the javelin.before the 1986 change in javelins , some of the best throwers in the world would throw the javelin with as little as 30 degree angle but greater speed because they were able to hold onto the javelin for longer , producing more force . Good throwers still use this method but the most commen method is releasing the javelin at about a 40 degree angles,causing a longer flight for the javelin.

What is Turning effect of force?
rotator
Does a 10lb catapult launch further than a 3lb one?
Usually yes...but it depends on the angle of trajectory, weight and aerodynamics of the thing being catapulted, the length of the "arm" of the catapult, and the amount of force that the catapult is set to hurl the object. Example: a feather on the 10lb catapult which is set at a high trajectory and a low force will go almost nowhere while a stone from a 3 pound catapult will go much farther if it is set on a perfect trajectory and maximum force.
What force is the upward force exerted on any object in a fluid?
The upward force exerted on an object in a fluid is buoyancy.
