6 When a man is standing in an ascending lift that has a constant upward acceleration, the magnitude of the force exerted on the man's feet by the floor is always A equal to the magnitude of his weight. B less than the magnitude of his weight. C greater than the magnitude of his we...
So at this point when studying constant acceleration weKinematic Equations About to Be Shown Or Developed Are

Identify the acceleration of the car. Here, it's clearly stated as 4 m/s^2. This is constant acceleration because it does not change over time; the car's acceleration is the same throughout the problem. Step 3 Find the initial velocity and displacement. The initial velocity is clearly st...
In other words, we can say that the net force on a particle is directly proportional to the mass and the acceleration of the particle.Answer and Explanation: Given : The acceleration of an object is constant and its mass increases. Applying the Newton's ...

How can a velocity/time graph show acceleration? If a particle has a non-zero acceleration and a non-zero constant speed at all times, what is the angle between the particle's velocity and acceleration? Is motion considered the same as speed?
