What else can I help you with?
Which direction does the centripetal acceleration point?
Centripetal acceleration is acceleration towards the center of the movement.
Describe the motion of a person in terms of acceleration?
If the person is walking, after electric impulses tell your feet to move, muscles contract. Your feet, relative to the floor accelerate the rest of your body ahead of them, by means of friction. Too much acceleration can crush a person though, something like 12g?
What is an acceleration sensor?
What kind of acceleration sensor are you referring too?
Suppose the force F doubles what will happen to the acceleration?
acceleration doubles too.
What kinds of butterflies there are?
Too many kinds to list.
How do you use 2 dimensional kinematics?
basically projectile motion is the best example in our earth of 2-d kinematics....uses of projectile motionProjectile motion is applied in most of our daily activities like playing cricket, playing badmintion. Jumping of animals is also an example of projectile motion. Throwing of missile from cannon too a good use of projectile motion.
What are the conditons for an object to stay at rest to keep moving at constant velocity or to move with increasing velocity?
When the object is at rest, the acceleration is zero. so the net total force acting on the body from all directions should be zero. when the object is moving with constant velocity, the acceleration is zero, so in this case too, after the motion is started, the force on the body should be zero. when the velocity is increasing, some acceleration is present, so some force should be present in the direction of the motion. These are the various cases which can be explained by the equation: Force = Mass * Acceleration. here the mass remains constant, so acceleration depends on the net force/
What happens to horizontal acceleration if the angle of a mass is increased?
If the angle of a mass is increased, the horizontal acceleration would decrease due to the component of gravitational force acting perpendicular to the direction of motion increasing. This component would counteract some of the horizontal acceleration.
Why is uniform circular motion an example of uniform acceleration?
With no acceleration a body moves at constant speed in a straight line. However to travel a circular path you have to apply a force to bend the path of the object form a straight line into a circle. The application of this force is an acceleration. Note too that because the path is circular, the SAME force is required at all points of the circle this makes the acceleration UNIFORM. If you do not believe this, tie something to the end of a piece of string and swing it round your head in a circle. You will feel the string pulling your hand as you do this, this is the force causing the acceleration.
Measures an objects tendency to remain at rest or keep moving with constant velocity?
When the object is at rest, the acceleration is zero. so the net total force acting on the body from all directions should be zero. when the object is moving with constant velocity, the acceleration is zero, so in this case too, after the motion is started, the force on the body should be zero. when the velocity is increasing, some acceleration is present, so some force should be present in the direction of the motion. These are the various cases which can be explained by the equation: Force = Mass * Acceleration. here the mass remains constant, so acceleration depends on the net force
What is the mathematical formula for acceleration?
Actually me too was searching for it
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
