If you know the Force (in Newtons) being applied on it, and its mass (in kg) you can use the equation- a=F/m.
or
If you know the final speed (in meters per second), the initial speed and the time (in seconds), use the equation a=[final minus initial]/time.
To determine the acceleration of an object, you need to calculate the change in velocity over a specific period of time. Acceleration is calculated by dividing the change in velocity by the time taken for that change to occur. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
You must calculate the change in velocity during each unit of time.
Changing at a constant rate equal to acceleration.
The object's acceleration must be in the negative direction, opposing its velocity in the positive direction. This negative acceleration is also known as deceleration and causes the object to slow down.
Fnet = m*anet where m is the mass of the object, Fnet is the net force on the object, and anet is the net accel. on the object. Keep in mind that force and acceleration are vectors and you must take into account the direction that they are in.
velocity
An object must experience a net force in order to accelerate. This force causes the object to change its speed, direction, or both, resulting in acceleration. The magnitude of the acceleration is directly proportional to the force applied on the object.
For acceleration to occur, there must be a change in an object's velocity over time. This change can happen by increasing or decreasing the object's speed or by changing its direction of motion. In essence, acceleration is a measure of how much an object's velocity changes per unit of time.
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
According to Newton's Second Law, Force = mass*acceleration. This means that in order to know the overall force of an object, acceleration and mass must be known. If the object is in free-fall (falling down with no other forces acting on it), acceleration due to gravity is 9.81(m/s^2). If the object is not in free-fall, one must determine acceleration by using Newton's first equation of motion: vf = vi + a∆t, where vf is the final velocity, vi is the initial velocity, a is acceleration and ∆t is the time period between the measurement of the initial velocity and the final velocity. By shifting the equation around, the equation: a = (vf-vi)/∆t is determined. Multiply acceleration times mass and you will obtain the object's force.
To change velocity, an object must undergo acceleration. Acceleration is the rate of change of velocity with respect to time. This can be achieved by applying a force on the object in the direction of desired velocity change.
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
