There are two problems with this question.
The less obvious one is: What do you mean by "a negative effect" on velocity ?
ANY force that acts in the direction opposite to the direction of the velocity will
cause the magnitude of velocity to decrease, which in itself is pretty negative.
If the force continues to act long enough, it will eventually cause the velocity
to reverse its direction, which is about the most negative effect you can have
on velocity.
What else can I help you with?
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.
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.
Can the velocity of an object be negitive when its acceleration is positive?
That just means that the velocity and acceleration are in oppposite directions ... exactly the situation when a car is slowing down for a stop, or a ball is tossed upward and hasn't reached the peak yet.
Is the velocity of the ball changing during the entire flight or just at certain times?
The velocity of the ball is changing throughout its flight. This is because the ball experiences an acceleration due to factors like gravity, air resistance, and any applied forces. These changes in velocity result in the ball's motion being constantly in flux.
Can acceleration be positive while velocity is negative for an object?
Acceleration can be positive while velocity is negative for an object. For example, If the object (like a car) is moving in a negative direction (let's say west) and the brakes are applied to slow the car down. This causes the car to accelerate (commonly called deceleration) in the positive direction until it stops. Mathematically, one could work this out by taking the change in velocity over the change in time. acceleration = (V final - V initial) / time In this example, let's suppose V initial is -20 m/s and V final is -10 m/s, and the time for the velocity change is 5 seconds. Then acceleration would be : -10m/s - (- 20 m/s) divided by 5 seconds = 2m/s/s Thus, we see, an example of negative velocity yielding positive acceleration from an outside net force on the object via the brakes.
How do you find the final velocity if the acceleration is negative?
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
When final velocity is less then initial velocity of an object the acceleration is negative?
yes, many answers in applied maths come out as negative, it just means that the force or object is slowing down or reversing. in this case there is a negative acceleration as its slowing down
Can an object's acceleration be a negative number?
Yes, an object's acceleration can be a negative number if it is experiencing deceleration or moving in the opposite direction of its positive acceleration. Negative acceleration represents a decrease in velocity over time.
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 do constructive and destructive forces effect the earth's surface?
because they just do XD
What are the conditions of an object to stay at rest to keep on moving at constant velocity or to move with increasing velocity?
If the sum of all forces on an object is zero, then the object remains in constant velocity. Constant velocity means motion in a straight line at a constant speed. "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. If the sum of the forces is in the same direction as the object's motion, then the object must speed up.
What was a negative effect of growing tobacco?
it ruined soil after just a few years
Why do we need scientific forces?
Forces exist whether there are people, animals, and plants or not. Science just looks at how forces work, and how they relate to movement, acceleration, velocity, work, power, and so forth. So it is not a question of if 'we need scientific forces', at all.
Can the velocity of an object be negitive when its acceleration is positive?
That just means that the velocity and acceleration are in oppposite directions ... exactly the situation when a car is slowing down for a stop, or a ball is tossed upward and hasn't reached the peak yet.
Is it possible to have a negative speed?
No, Speed is always greater than or equal to zero. However, velocity can be negative, which just means you have a positive speed in the opposite direction! (scalar(number) versus vector).
What are the conditions for an object to stay at restto keep moving at constant velocity?
"Constant velocity" means neither the speed nor the direction of the object's motion is changing. "Rest" is just one kind of constant velocity ... the kind with zero speed. The condition for an object's velocity to remain constant is: Either there are no forces acting on the object, or else all of the forces acting on it add up to zero. If there is any NET force acting on the object, then its velocity will change ... it will either speed up, slow down, or curve in a new direction.
What is the difference between speed time and velocity time graphs?
This is a really good question. Speed and velocity are similar. Velocity is just speed, but a direction is included. Say you are driving a car. Driving forward is positive velocity, while driving backwards is negative velocity. Speed is what a radar gun would show about the car either way, because it can't tell if the car is moving forward or backward. Therefore, you can have negative velocity, but there is no such thing as negative speed. A speed graph will always stay positive, while a velocity graph can go negative at some places, though it doesn't have to. HOPE THIS HELPS!!! Addendum: Only in ONE-dimensional motion can "Velocity vs Time" graphs be truly drawn; as only in this dimension can direction be indicated by +/- sign. In 2-D and 3-D motion, the graph equivalent must be "Speed vs Time" because these graphs do not indicate direction.
