The gravitational attraction between two objects grows in strength with each object's mass. The gravitational force between two objects doubles when one of the objects' masses doubles.

The acceleration that gravity imparts to objects falling freely is used to quantify gravity. At the surface of the Earth, gravity accelerates at a rate of around 9.8 meters (32 feet) per second. As a result, an object in free fall accelerates by 9.8 meters per second for every second that it is falling.

The gravitational field strength of the Earth is 9.8 N/kg. Accordingly, an item will feel 9.8 N of force for every kg of mass. That weight of a thing is lower if the gravitational field is weaker. The Moon, for instance, has a gravitational field that is 1.6 N/kg strong.

The acceleration due to gravity at the surface of Neptune is calculated to be 10.08 m/s².

Here, we can apply the concept of Newton for the definition of the gravity of a planet, for which he defines that this is proportional to the product of the mass of the planet by the universal gravitational constant, and inversely proportional to the square of the radius of the planet. Mathematically this can be described as

g = GM/r²

where,

G is universal gravitational constant

M is the mass of the planet

r is the radius of the planet

Given that,

Mass of the planet M = 1.025 × 10²⁶ kg

Diameter of the planet = 49532 km = 49532 × 10³ m

Radius of the planet = 24766 × 10³ m

After putting the values into the equation above, we have,

g = GM/r² = (6× 10⁻¹¹) (1.025 × 10²⁶)/(24.7 × 10⁶)² = (6.15 × 10¹⁵)/(24.7 × 10⁶)² = 10.08 m/s²

Every body in the universe attracts every other body with a gravitational force that decreases with distance as 1/r2. But actually he knew more about the gravitational force: from the fact that bodies of different masses near the earth’s surface accelerate downwards at the same rate, using F = ma (Second Law).

If two bodies of different masses have the same acceleration they must be feeling forces in the same ratio as their masses (so a body twice as massive feels twice the gravitational force), that is, the gravitational force of attraction a body feels must be proportional to its mass.

Newton’s first clue that gravitation between bodies fell as the inverse-square of the distance may have come from comparing a falling apple to the falling moon, but important support for his idea was provided by a detailed description of planetary orbits constructed half a century earlier by Johannes Kepler.

Answer:

To solve this problem, you can use the principle of transverse static equilibrium. This states that the sum of the forces acting on an object must be equal to zero for the object to be in equilibrium. In this case, the forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod.

First, you can find the weight of the rod by multiplying its mass by the acceleration due to gravity:

Wrod = mrod * g

= 0.7 kg * 9.8 m/s^2

= 6.86 N

Next, you can find the weight of the 4.0-kg mass by multiplying its mass by the acceleration due to gravity:

W1 = m1 * g

= 4.0 kg * 9.8 m/s^2

= 39.2 N

You can find the weight of the 2.0-kg mass in the same way:

W2 = m2 * g

= 2.0 kg * 9.8 m/s^2

= 19.6 N

To find the tension in the strings, you can use the principle of transverse static equilibrium. The forces acting on the rod are the tension in the strings, the weight of the rod, and the weight of the masses hung on the rod. You can represent these forces as vectors acting at the points where the strings are attached to the rod. The vectors representing the tension in the strings will be equal in magnitude but opposite in direction. The vectors representing the weight of the rod and the masses will act vertically downward.

The total kinetic energy gained by the object when accelerating a 20-n object from rest across a horizontal frictionless table is 10.0 J.

To determine the total kinetic energy gained by the object, we can use the work-energy principle, which states that the work done on an object is equal to the change in kinetic energy of the object.

Work done = change in kinetic energy

W = Kf - Ki

where

W = work done (10.0 J)

Kf = final kinetic energy

Ki = initial kinetic energy (0 J, since the object is at rest)

Given the information provided, we know that a total of 10.0 J of work is done in accelerating the 20-n object from rest.

So,

Kf = W + Ki

Kf = 10.0 J + 0 J

Kf = 10.0 J

Forces acting upon a 100-kg crate which is sliding down an inclined plane, the plane is inclined at an angle of 30 The coefficient of friction between the crate and the incline is 0.3. the net force of the crate is 230N.

Solution:

Given:

Mass of crate=100kg

Angle of inclination=30°

coefficient of friction=0.3.

Now,

F∥=mgsinθ=(100)(10)0.5=500N is the force acting parallel to the inclined plane.

then,

Normal force= mgcosθ=(100)(10)(0.9)=900N

then, frictional force =

Frictional force=μkF⊥=(0.3)(900)=270N

Finally the net force = F∥-frictional force
