How force affects mass and acceleration?
force is directly proportional to acceleration and acceleration is inversely proportional to mass of the body
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
When a body moving with uniform and negative acceleration?
When the body is in simple hermonic motion
Is it possible for a body to have acceleration when moving with constant veloctiy?
No, because acceleration is the rate of change of velocity.
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
When are velocity and acceleration perpendicular to each other?
When body is moving in a circle.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
What is the direction of average acceleration?
The direction of average acceleration is downwards, in the direction of gravity. This is because gravity affects all objects, even objects that are moving in other directions.
If the displacement of a body is proportional to square of time will the body be moving with uniform velocity or uniform acceleration?
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
What can cause velocity to change?
acceleration, due to a force the moving body is affected by. SUM[Forces] = mass * acceleration --> change in speed.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
