A car can have a negative acceleration and be speeding up.
A negative acceleration determines the direction of the acceleration
A car with forward acceleration will speed up in the forward direction
A car moving forward with a negative acceleration will slow down
A car not moving with a negative acceleration will speed up in the backward direction
A car moving backward with a negative acceleration will speed up in the backward direction
What else can I help you with?
Is there a negative number of electrons?
No, electrons cannot have a negative number as they are fundamental particles with a negative charge. The number of electrons in an atom or a system is always a whole number and cannot be negative.
What system gets your body ready for emergency by increasing Adrenalin and slowing digestion down?
The sympathetic nervous system.
For a given value of net force what would increase acceleration for a system?
To increase acceleration for a given net force, you can decrease the mass of the system. This is because acceleration is inversely proportional to mass when net force is constant (F = ma). Alternatively, you can increase the net force acting on the system.
What is the polarity of wires when you have a black and a white wire on a 12 volt radar?
In a DC circuit, the black wire is typically the negative (-) wire and the white wire is the positive (+) wire. To ensure proper connection, always check the specific wiring instructions for the radar system you are using.
Will this entropy change by positive or negative?
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
A classmate in the physics state that the negative acceleration always mean that a moving object is decelerating is that true?
No, that statement is not entirely true. Negative acceleration means the velocity of the object is decreasing, which could be due to deceleration (slowing down) or changing direction. Positive acceleration means the velocity is increasing.
Does negative acceleration have constant acceleration?
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
It is physically impossible for an object to have a negative acceleration and yet be speeding up?
An object with a negative acceleration is slowing down, not speeding up. Negative acceleration means the object is decelerating or moving in the opposite direction of its velocity, causing it to slow down. Objects speed up when their acceleration is in the same direction as their velocity.
What is the part of the autonomic nervous system that is always active and acts as an acceleration for organs?
sympathethic nervous system
Is potential energy in k-shell is negative then why?
bcoz the energy of bound system is always negative
Can binding energy be negative?
No, binding energy cannot be negative. Binding energy is always a positive quantity that represents the energy required to hold a system together. If the binding energy were negative, it would imply that the system is in an unstable state.
What is the impact of negative friction on the efficiency of a system?
Negative friction, also known as drag or resistance, can significantly reduce the efficiency of a system by slowing down the movement of objects or components within the system. This can lead to increased energy consumption, decreased performance, and potential damage to the system over time. In essence, negative friction hinders the smooth operation of a system, ultimately impacting its overall effectiveness and productivity.
When will be entropy negative?
Entropy is a measure of disorder in a system and is always equal to or greater than zero according to the second law of thermodynamics. Entropy cannot be negative in a closed system.
What detects gravity and linear acceleration?
The inner ear's vestibular system is responsible for detecting linear acceleration, which includes changes in motion like speeding up or slowing down. Gravity is sensed by the otolith organs within the vestibular system, specifically the utricle and saccule, which detect changes in head position and orientation relative to gravity.
How can the concept of negative work in physics affect the overall dynamics of a system?
Negative work in physics occurs when the force applied to an object is in the opposite direction of its motion. This can result in a decrease in the object's kinetic energy and a change in its velocity. In a system, negative work can lead to a decrease in the overall energy and momentum, affecting the system's dynamics by slowing down or changing the direction of its motion.
Can the normal force be negative in a physical system?
No, the normal force cannot be negative in a physical system. It always acts perpendicular to a surface and opposes the force pushing against it.
Why is negative cam provided on the air starting system in a diesel two stroke engine?
negtive means downward and inward movement of cam. Due to ease to reversing and reduce acceleration forces cam is negative
