Acceleration is the rate that speed changes.
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
no
We have constant acceleration all the time. Its called gravity. Gravitational acceleration is 9.8... m/s^2
Acceleration is the time rate of change of speed. Acceleration = speed/time.
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.
No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
no
In that case, the speed will increase.
The acceleration is the same direction of the velocity
Yes as there is no acceleration then the speed which is already there would remain the same as no change in speed is brought out.
Speed increase constantly.
Speed increase constantly.
No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.
We have constant acceleration all the time. Its called gravity. Gravitational acceleration is 9.8... m/s^2
No. Acceleration only affects velocity in one particular direction (same direction as acceleration). Speed is the summation of velocities in all directions.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
