What does the acceleration depend on?
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
As the force acting upon an object is increased, the acceleration of the object is increased.
As the mass of an object is increased, the acceleration of the object is decreased..
How is acceleration dependent on speed and direction?
The acceleration of the object is dependent upon this velocity change and is in the same direction as this velocity change. … Objects moving in circles at a constant speed accelerate towards the center of the circle. The acceleration of an object is often measured using a device known as an accelerometer.
Does acceleration increase with height?
The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.
When acceleration is zero What happens to velocity?
Acceleration is the change in velocity per unit time. So when acceleration is zero, there is no change in velocity i.e,velocity is constant. When acceleration is zero …that means the rate of change of velocity is zero ..
What is tangential acceleration?
Linear or tangential acceleration refers to changes in the magnitude of velocity but not its direction. We know from Uniform Circular Motion and Gravitation that in circular motion centripetal acceleration, ac, refers to changes in the direction of the velocity but not its magnitude.
What are the 3 laws of motion?
The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.
Does acceleration affect speed?
The direction of the acceleration determines whether an object will slow down, speed up, or turn. is in the same direction as the object is moving, the speed of the object increases. The car speeds up. acceleration is opposite to the motion, the speed of the object decreases.
Can an object speed up with negative acceleration?
An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. … Subtracting from the value of the velocity could increase the speed of an object if the velocity was already negative to begin with since it would cause the magnitude to increase.
Does the initial velocity affect acceleration?
3. Initial velocity is independent of the slope of the graph; that is, the acceleration. An object thrown downward still accelerates after release at the same rate as an object that is dropped.
What is acceleration vs velocity?
Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.
Does constant speed mean no acceleration?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. … Since it travels in a straight line, its direction does not change.
