What else can I help you with?
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.
How do you find the initial velocity given only the distance and the time traveled?
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.
How do you find a final velocity without distance but given time?
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
How do you find acceleration falling object with only speed and distance?
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
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
What information do you need in order to find a object's acceleration?
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.
How to find the initial velocity of an object in motion?
To find the initial velocity of an object in motion, you can use the equation: initial velocity final velocity - (acceleration x time). This equation helps you calculate the starting speed of the object based on its final velocity, acceleration, and the time it took to reach that final velocity.
What is the final velocity of an object when using the momentum formula?
The final velocity of an object can be calculated using the momentum formula, which is: momentum mass x velocity. To find the final velocity, rearrange the formula to solve for velocity: velocity momentum / mass.
How do you calculate the change in velocity of an object?
To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.
How can one determine the final vertical velocity of an object?
To determine the final vertical velocity of an object, you can use the equation: final velocity initial velocity (acceleration x time). This equation takes into account the initial velocity of the object, the acceleration due to gravity, and the time the object has been falling. By plugging in the values for these variables, you can calculate the final vertical velocity of the object.
How can one determine the final velocity of an object using the concept of momentum?
To determine the final velocity of an object using the concept of momentum, you can use the equation: momentum mass x velocity. By calculating the initial momentum and final momentum of the object, you can then solve for the final velocity using the formula: final velocity final momentum / mass.
How do you find final and initial velocity?
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.
Is it possible for the final velocity of an object to be negative?
Yes, it is possible for the final velocity of an object to be negative. This means that the object is moving in the opposite direction of its initial motion.
How can one find the acceleration of an object using the given distance and time measurements?
To find the acceleration of an object, you can use the formula: acceleration change in velocity / time taken. If you have the distance and time measurements, you can calculate the velocity by dividing the distance by the time. Then, you can find the change in velocity by subtracting the initial velocity from the final velocity. Finally, divide the change in velocity by the time taken to find the acceleration.
How to find acceleration from velocity and time?
To find acceleration from velocity and time, you can use the formula: acceleration (final velocity - initial velocity) / time. This formula calculates the change in velocity over a specific time period, giving you the acceleration of an object.
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
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.
What is the change in time formula for calculating the velocity of an object?
The change in time formula for calculating the velocity of an object is: velocity (final position - initial position) / (final time - initial time).
