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.

What must you calculate to determine the accerleration of an object?
To determine the acceleration of an object, you must calculate its change in velocity per unit of time.
What must you calculate to determine the acceleration of an object?
You must calculate the change in velocity during each unit of time.
What is the formula you use to determine acceleration?
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.
If an object falls with constant acceleration the velocity of the object must?
Changing at a constant rate equal to acceleration.
What point must be chosen to determine the motion of an object?
A reference point must be chosen to determine the motion of an object.
To calculate acceleration of an object you must find change in?
velocity
For an object to be in projectile motion and what force must be acting on it?
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
How do you find force of an object?
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 determine acceleration you must know the change in velocity during each unit of what?
"time"
When An object speeds up it has what acceleration?
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).
What must be known to determine the weight of an object?
Weight is equivalent to the force due to gravity. To determine weight, you must know both the mass of the object and the acceleration due to gravity in the place that the object resides..Weight = m * ag.where:m = the mass of the objectag = the acceleration due to gravity (-9.8 m/s2 on Earth at sea level).If you know both the mass of the object and the mass and size of the planet the object is being weighed on, then you can calculate the force due to gravity (weight) as:.Weight = G * mo * mp / r2.where:G is the gravitational constant of the universe (6.67 * 10-11 m3kg-1s-2)mo is the mass of the object being weighedmp is the mass of the planetr is distance from the center of the planet to the center of the object
