Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
What is negative shear and Positive shear in beams?
The difference between a positive shear and a negative shear is the direction the beam is distorted into. A force that tends to shear the left portion of the beam upward with respect to the right portion is said to produce a positive shearing force.
How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
How are multiplying integers and dividing integers alike?
a negative x a negative= a positive, a positive x a positive= a positive, a negative x a positive= a negative, and a positive x a negative= a negative. Same thing with division. a negative divided by a negative= a positive, a positive divided by a positive= a positive, a negative divided by a positive= a negative, and a positive divided by a negative is a negative. U see?
What is negative seven in Parentheses to the second power?
positive 49 Because a negative times a negative is a positive. -7*-7=49. positive * positive = positive negative * negative= positive positive * negative = Negative
Is the gravitational force negative?
No, the gravitational force is not negative. It is always positive and attractive, meaning it pulls objects towards each other.
Why is gravitational potential always negative?
because gravity is a force that acts down on an object. In physics up is positive and down is negative
What is negative and positive gravity?
"Negative gravity" is not a scientific concept. Gravity is a fundamental force of attraction between masses. "Positive gravity" is simply the normal gravitational force experienced on Earth, pulling objects towards the center of the planet.
Why the gravitational force is a negative value?
Gravitational force is a vector quantity, meaning it has both magnitude and direction. The negative sign indicates that the force acts in the opposite direction to the reference direction chosen, typically taking downward as positive. This convention helps to easily incorporate the effects of gravitational forces in mathematical equations.
What is Mass and Charge?
Mass of a body is a positive quantity. The gravitational force between two masses is always attractive. Electric charge can be positive or negative or zero.
Why gravitationalforce is taken negative in projectile motion?
Gravitational force pulls downward. If you take the upward direction as positive, then any force that pulls downward will be negative. It is a matter of definitions; you can just as well define up as negative, and down as positive. It doesn't really matter much, one way or the other.
Why does an electric force stronger than gravitational force?
The electric force is stronger than the gravitational force because electric charges can be positive or negative, allowing for attractive and repulsive interactions, while gravity is always attractive. Additionally, the strength of the electric force is determined by the charge of the particles involved, which can be much larger than the masses involved in gravitational interactions.
Which universal force can repel as well as attract?
The gravitational force is proportional to the product of the two masses involved. The product is always positive, since mass is always positive. The electrical force is proportional to the product of the two charges involved. The product can be positive or negative, since either charge can be positive or negative.
What force gravitational or electrical repels as well as attracts?
The electrical force can repel as well as attract. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other. An example of this is when two positively charged particles repel each other, but a positively charged particle and a negatively charged particle attract each other.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
Is lightning a positive or negative force of nature?
Lightning is a negative force of nature.
A force is applied to the right is positive or negative?
It is positive
