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.
A lead bullet moves horizontally with a velocity of 130 ms-1 and embedded into a cement wall after collision. If the specific heat capacity of lead = 130 JKg-1°C-1 and all heat pro
1. What is the principle of gas filled detectors? 2. What are nuclear radiations or particle detectors?
Is it determined by acceleration or velocity? Force or momentum?
Sliding versus Static Friction: Friction force is the force exert by a surface as an object moves crosswise it or makes an effort to move across it. Two types of friction force
