The net force is the vector sum of all the forces acting on the object....So that is...(20+10=30)N acting in the same direction.........
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
The net force acting on a 1-kg freely falling object is equal to its weight, which is the force of gravity pulling it downward. This force is approximately 9.8 newtons (N) on Earth.
No, Newton's third law states that for every action there is an equal and opposite reaction. In the case of a freely falling body, gravity is the dominant force acting on the body, causing it to accelerate downward. This is described by Newton's second law, which states that the force acting on an object is equal to its mass times its acceleration.
Net force=ma=25N
Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
Ten newtons downward, by definition.
It doesn't, since the conditions don't apply. The conditions for Newton's First Law are that there is no net force on an object - there must be no force on the object, or the vector sum of the forces must be zero.
It sure does! Look up Newton's law of universal gravitation. Basically it states that each object exerts the exact same amount of force upon the other. For example, your weight on Earth is exactly the same as Earth's weight on you. And if you are freely falling toward the Earth, then the Earth is freely falling toward you. You don't notice it, because the accelerations are inversely proportional to the masses, and the Earth has quite a bit more of that than you have.
No, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the force exerted by the object on the Earth is equal in magnitude to the force exerted by the Earth on the object.
Yes, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. When a falling object hits the ground, the ground applies an upward force on the object, resulting in the object coming to a stop.
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
An object falling freely under gravity is known as a free-falling object, where gravity is the only force acting on it. In the absence of other forces like air resistance, the object accelerates at a constant rate of 9.8 m/s^2 (approximately) towards the Earth's surface.
