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.
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
Yes.
To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.
To find the final velocity of an object, you can use the kinematic equation: final velocity = initial velocity + (acceleration * time). If acceleration is constant, you can also use the equation: final velocity = initial velocity + (2 * acceleration * distance). The initial velocity can be found by measuring the velocity of the object at the beginning of its motion using a speedometer or other measuring device.
The equation that relates acceleration (a), initial velocity (u), final velocity (v), and time (t) for an object under constant acceleration is: v = u + at.
The equation to find acceleration is acceleration = change in velocity / time taken. This equation shows how much an object's velocity changes over a certain period of time, resulting in the acceleration of the object.
The equation that relates the distance traveled by a constantly accelerating object to its initial velocity, final velocity, and time is the equation of motion: [ \text{distance} = \frac{1}{2} \times (\text{initial velocity} + \text{final velocity}) \times \text{time} ] This equation assumes constant acceleration.
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 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 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.
Accelerating...or was accelerating.
You can calculate the time to accelerate using the formula, time = (final velocity - initial velocity) / acceleration. To do this, you need to know the initial velocity, final velocity, and acceleration of the object. Plug these values into the formula to find the time it takes to accelerate.
When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.
To find acceleration, you subtract the initial velocity from the final velocity and then divide by the time taken to achieve the change in velocity. The formula for acceleration is (final velocity - initial velocity) / time.
