Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?

The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)
Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.

What are the fomulas for incline plane?
( Assuming mass of object on incline plane is in kilograms (kg) ) . Force pulling down incline on object (kilogram force) = object mass * sin (incline angle) . Force of object acting on and normal to incline (kilogram force) = object mass * cos (incline angle) . Mechanical Advantage = 1 / ( sin ( incline angle ) )
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
What is the acceleration of an object that travels 8 meters in 1 second 8 meters in the 2nd second and 8 meters in the 3rd second?
Acceleration is the increase in speed from one unit of time to the next, so the described object has no acceleration. Its speed is constant.
What the relationships between the surface area of an object and the volume as the object increases in size?
They both increase. The rate of increase of the surface area is equivalent to the rate of increase of the volume raised to the power 2/3.
If mass increases and there is no friction would the acceleration of an object increase when place on an incline plane?
Yes. The acceleration is directly proportional to the objects mass.For objects with constant mass however, the acceleration will remain constant.
If you increase the force on an on object it's acceleration does what?
The Acceleration Increases.
If you increase the force on an object what happens to the acceleration?
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
If you increase the force on an on object it's acceleration?
It increases
What happens to an objects acceleration if you increase the force on the object?
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
What happens to an object's acceleration as the size of the force acting on the object increases?
F=m.a , a=F/m; acceleration is directly proportional with force. acceleration increase while force increase.
What increases as force increases?
F=ma, or force equals the product of mass and acceleration. Assuming that the mass of the object does not change, then acceleration increases as force increases.
How do you measure the acceleration of a moving object of an object at an incline?
with a speed gun
When the mass of an object increases how does the object's acceleration change?
As mass increases acceleration decreases.
What happens to the force of an object if the object increases?
The acceleration increases.
Can a object with no acceleration be stationary?
If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.
What happens to the acceleration of an object as its mass decreases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
