Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction.
It is not true, the object will accelerate only in the x-direction, but it may be traveling in the y-direction and it could continue to do so making the path it follows a parabola. Think about a ball kicked off a cliff. There is a net force only in the y-direction (gravity) so the ball will accelerate downwards while continuing with a constant horizontal velocity.
How do you calculate tensile strength? Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected
The force is in Newton The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 10 3 kg/m 3 ),
