What else can I help you with?
Can the speed of the particle ever be negative if so give an example if not explian why?
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
Why can't kinetic energy be negative?
Kinetic energy cannot be negative because it is a measure of an object's motion and velocity, which are always positive values. Negative kinetic energy would imply that an object is moving in the opposite direction of its velocity, which is not physically possible.
Is the momentum of an object always positive?
Depending on how you define it. Momentum is always given positive units, but sometimes when considered in a relative view, it can be in a negative direction making the overall value negative too (while mass is always positive, velocity might be in a negative direction where e.g. two masses are moving in opposite directions).
Explain the difference between acceleration and deceleration?
When an object is moving with different velocity with respect to time then the object is in acceleration or decceleration mode. If the rate of change of velocity is positive then it is said to be accelerated, if its negative it is said to be deaccelerated.
Can the speed of the particle ever be negative if so give an example if not explain why?
No, the speed of a particle cannot be negative. Speed is a scalar quantity and is always positive, representing the magnitude of the velocity of an object. Negative values are used to represent the direction of motion in one-dimensional motion.
Why is -x cube always negative for any nonzero value of x?
The premise of your question is false: -x³ is positive if x is negative.
Explain Why the product of two nonzero absolute values is always a positive number?
The absolute value of a number is its distance from zero on the number line, so it is always non-negative. When you multiply two nonzero absolute values, you are essentially multiplying two non-negative numbers together. In multiplication, a positive number multiplied by a positive number always results in a positive number, hence the product of two nonzero absolute values is always positive.
Can a body have negative speedwhy?
No. The speed is the length of the velocity vector, and that is always zero or positive.
The sum of zero and a negative integer is always sometimes or never zero?
The sum of zero and a negative integer can never be zero - it will always be negative and nonzero. Although zero is also an integer, it is neither negative nor positive and cannot be the other integer used.
Can the speed of the particle ever be negative if so give an example if not explian why?
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
Would a positive multiplied by a negative be a positive?
No. A positive times a negative is always negative. A negative times a negative is always a positive.
When dividing a positive number by a positive number the quotient is?
The answer is always positive. If the signs are the same (positive by positive, negative by negative), then the quotient is always positive. If the signs are different (positive by negative, negative by positive), then the quotient is always negative.
When you divide a negative with negative do you get a positive or negative?
always a positive
When a negative number is subtracted from a positive number is the difference always positive?
Yes, a negative number subtracted from a positive number will always be positive. Subtracting a negative number is the same as adding the opposite of the negative number. The opposite of a negative number is always positive. A positive number plus a positive number is always positive.
What is absolute value of the opposite of a nonzero rational number?
The absolute value is always positive.
Does a positive minus a negative equal a positive or negative?
Always positive.
Why can't kinetic energy be negative?
Kinetic energy cannot be negative because it is a measure of an object's motion and velocity, which are always positive values. Negative kinetic energy would imply that an object is moving in the opposite direction of its velocity, which is not physically possible.
