What is the net external force on an object in free fall?
The net external force is just the weight of the object (F = W). Substituting into the second law equation gives: a = W / m = m * g / m = g . The acceleration (change of velocity) of the object then becomes the gravitational acceleration.
What is the force of gravity acting on a 10 kg object?
The Earth’s gravitational field strength (g) is 10 N/kg. This means that for each kg of mass, an object will experience 10 N of force.
What is the force of gravity on a 1kg object?
On Earth, an object with a mass of 1kg will experience a force of 10N due to gravity, i.e. the weight of a 1kg mass is 10N.
Is the gravity a property of earth only?
Gravity is not a property of the earth alone. Every object in the universe exerts a force on every other object. This force is known as the gravitational force.
What are the two factors on which effect of force depends?
1.it depends on the amount of applied on the object, 2.it also depends on the how much friction is there, 3. and it it also depends on the mass and surface of the object. The factor of a force depends on two things: 1. the amount of a force applied.
What are the two factors which affect moment?
The size of a moment depends on two factors:
- the size of the force applied.
- the perpendicular distance from the pivot to the line of action of the force.
What are the factors which affect the force?
Force and Pressure | Short/Long Answer Questions Solution: Factors on which moment of force depends are: (i) The magnitude of the force applied. (ii) The distance of line of action of the force from the axis of rotation.
On what factors pressure depends?
Pressure = Force/Area So, the pressure depends on force applied and the area on which force is acting. Answer: Pressure is defined as thrust per unit Area. It depends on mass of the object, acceleration of object, and area upon which force is acting.
