How big is the acceleration on nemesis inferno?
G-Force = positive 4.5g Maximum Velocity = 77kmph Hope this helps.
How do you calculate brake pedal force and deceleration?
when breaks are applied for moving car whose velocity will be decreases and finally car will be at rest position acceleration = (final velocity - initial velocity)/time taken = (0-u)/t = -(u/t) negative acceleration is called deceleration deceleration = - acceleration chennakesavarao@itimes.com
Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
How do you draw velocity and acceleration diagrams?
Velocity diagrams are drawn perpendicular to the link ....whereas acceleration diagrams are drawn by knowing the values 2 components radial or centripetal component and tangential component.......the radial component moves parallel to the link and perpendicular to the velocity diagram.....but the tangential component moves perpendicular to the link and parallel to the velocity diagram .
Why you calculate momentum?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
How are deceleration and acceleration related?
Acceleration and deceleration are related by their their sign. Acceleration is positive ( increase in velocity with time) and deceleration is negative (decrease in velocity with time).
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
How is motion demonstratd with snowboarding?
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
What is the action of an automobile if the velocity is positive and the acceleration is negative?
it will stop after some time
