An equal and opposite force is also applied to the object,
so that the vector sum of all the forces on it is zero.
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
angular acceleration
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.
Constant acceleration. Note that all orbits approximate this condition.
Changing at a constant rate equal to acceleration.
Yes, a falling apple meets that condition.
Wrong. An object maintains a constant velocity unless there is a change in mass, applied force, air resistance or some other external force.
There will by no change in the mass, which is constant, but the unbalanced force will cause the object to accelerate. Acceleration can be in a positive direction or a negative direction ("deceleration"), or it can be circular, in which the acceleration changes constantly, even if the velocity remains constant.
Object shows acceleration when the force applied on it is increased.
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
No. An object traveling at a constant velocity is not accelerating.
