differentiate gravitational force and acceleration due to gravity
Answer:
I hope this answer is correct
Explanation:
Difference Between Gravitation and Gravity
Gravitation is referred to the force acting between two bodies which can be represented as the F=(GM1M2)/R2 which means gravitation force is proportional to the product of the masses of the object 1 and object 2 and is inversely proportional to the square of the distance between them. The gravitational force between earth and any object is known as gravity.
Difference Between Gravitation and Gravity
Gravitation Gravity
It is a universal force It is not a universal force
It is a weak force It is a strong force
The force is F=(GM1M2)/R2 (G= gravitational constant) The force is F=mg (g=acceleration due to gravity)
The direction of gravitational force lies in the radial direction from the masses The direction of the force of gravity is along the line joining the earth’s center and the center of the body. Its direction is towards the center of the earth.
The force can be 0 when the separation between bodies is infinity The force of gravity can be 0 at the center of the earth
It requires two masses It requires only one mass

A weight force of 10 N force acts on an object while the object moves 20m along horizontal ground. How much work is done by the weight force on the object? a) 0.5 J b) 2 J c) 10 J d) zero e) 200 J I already know it's not 200 J because I got the question wrong. Please show work!
Answer:
e) 200 J
Explanation:
Work done by a force on an object is the energy required for a force to move that object over a distance. It can be calculated using the formula:
W = F × d
Where; W = work done
F = force applied
d = distance
According to this question, F = 10N, d = 20m
W = 10 × 20
W = 200 J or N/m

what is a multiple motion ? give example
Answer:when a body possesses more than one simple motion, it is called a multiple motion.
Explanation:you are traveling by a train. Your wrist watch is also sharing the linear motion of the train. But the hands of the watch are also undergoing rotational motion. Thus they have 2 kinds of motion, I, e, Multiple motion.so also the blades of the fan in the train have multiple motion (a linear motion of the train and the rotation).
A student throws a ball up straight up. What happens to the ball's energy as it rises?
Answer:
B. The kinetic energy of the ball change into potential energy as the ball rises.
Explanation:
This can seem a little bit confusing at first, but once you understand Kinetic Energy, you'll get it right away. Kinetic Energy is energy an object has when it is moving. So for example, you have kinetic energy when you run, a pen has kinetic energy when you drop it in class, and the ball has kinetic energy as it rises.
However, because of outside forces, objects with kinetic energy will eventually lose it. These forces can be anything from friction as an object slides across a surface, to the negative acceleration due to gravity.
In this question, the force working against the motion of the ball is gravity. As you know, when you throw something up, it has to come down, because of gravity. As the ball goes up, it has enough kinetic energy that it continues its upward motion, however it slowly looses that energy, causing it to slow to a stop before falling back to the ground.
On the way up, the energy of the ball changes from this kinetic (moving energy) to what we call potential energy. Potential energy is exactly what is sounds like, it is the potential for something to begin moving. So, as the ball goes higher, it has a lower chance of continuing to go up (meaning it's loosing it's kinetic energy) and higher chance of falling back down (meaning it's gaining potential energy).
Hope this helps.

How and why can two lethal elements combine to form an essential
compound for health?
Answer:
Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal
Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases
Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures
Explanation:
Mercury is a lethal element that also has harmful effects on the neurological system
Sulfur is lethal when too much of it is consumed

check all that apply
A. a basketball being shot toward the basket
B. a bowling ball rolling down the lane
C. a dog running along a sidewalk
D. a baseball hit for a home run
Answer: A. a basketball being shot toward the basket
Explanation: The definition of projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. So, the basketball is the object being thrown and the person throwing the ball is aiming it to go into the basket making that the path of trajectory. Hope that makes sense and helps!
