What else can I help you with?
When acceleration is less than 0 and velocity is less than 0 then speed is?
When acceleration is less than 0 and velocity is less than 0, the speed is positive. Speed is the absolute value of velocity, so it is always positive regardless of the direction of motion.
When an object's final velocity is less s acceleration?
When an object's final velocity is less than its initial velocity, it is said to be decelerating or slowing down. This can occur if the acceleration is in the direction opposite to the initial velocity, causing the object to decrease its speed over time.
If you increase the radius of circular motion then what is the centripetal acceleration?
That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
What effect does fraction have on the velocity of the ball?
The fraction of force affecting the ball determines its acceleration and, consequently, its velocity. A higher fraction of force results in greater acceleration and a higher velocity, while a lower fraction results in less acceleration and a lower velocity.

When acceleration is less than 0 and velocity is less than 0, the speed is positive. Speed is the absolute value of velocity, so it is always positive regardless of the direction of motion.

When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.
Which is greater in positive acceleration initial or final velocity?
In positive acceleration, the final velocity is greater than the initial velocity. This is because acceleration is the rate of change of velocity, so as time progresses, the velocity increases due to the acceleration.
When final velocity is less than initial velocity is an example of?
Deceleration (or negative acceleration).
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
An objects acceleration decreases as the objects mass?
force = mass * acceleration then mass and acceleration is inversly proportional. Actually mass is constant but when the speed increases the mass become less since acceleration and velocity is directly propotional thus acceleration increases too.....thx..with best regards..
What effect does fraction have on the velocity of the ball?
The fraction of force affecting the ball determines its acceleration and, consequently, its velocity. A higher fraction of force results in greater acceleration and a higher velocity, while a lower fraction results in less acceleration and a lower velocity.
How do you calculate deseleleration?
Deceleration (not deseleration) is the negative rate of change of velocity over time. Acceleration is [Final velocity - Initial Velocity]/Time. If the final velocity is less than the initial velocity, then the above quantity is negative and is termed deceleration. The instantaneous deceleration is dV/dt, the derivative of the velocity with respect to time. Sometime acceleration and deceleration are defined in terms of speed rather than velocity. This is not correct since it is inconsistent with the laws of motion.
What is newtons 2nd law of motion in simple terms?
It isn't really simple to explain; to get a thorough understanding, you MUST understand a few basic concepts. See below. But basically, a force will result in an acceleration; the amount of acceleration an object experiences will depend on the force (more force will result in more acceleration), and on the object's mass (more mass will result in less acceleration). The basic concepts that are important to understand are the following: * Acceleration as a rate of change in velocity - how fast velocity changes. * Both velocity and acceleration are vectors. * A reduction in speed is a change in velocity; so is a change in direction, even if the speed doesn't change. In this case, in physics you would still talk about "acceleration"; even though in popular terms, "acceleration" is usually understood as an increase in speed. * The NET FORCE must be considered - the vector sum of all forces that act on an object. It is quite common that a force acts on an object, but it doesn't accelerate - in which case there is a counter-force that is balancing the first force.
