As the velocity of particle in uniform circular motion is constant in magnitude but changes direction. So, the acceleration is also constant in magnitude but not in direction.

If the displacement of an object is proportional to the square of the time taken, the body is moving with a uniform acceleration because it will follow Newton’s second equation of motion for a particular initial velocity. From second equation ...

In the case of motion along a straight line, the distance covered and the magnitude of the displacement are the same. Because displacement is the shortest path between the initial and the search path. So, for a car moving on ...

Newton’s third law of motion states that to every action there is an equal and opposite reaction. A gun recoils due to reaction force of bullet fixed by it.

After half circle the given particle will reach the point opposite to the diameter i.e. from point “A” to point “B” (r + r = 2r {diameter}). And we know that displacement is the shortest path between starting and ending ...

The property of an object to resist any change in its state of motion or rest is called inertia. If an object is at rest, then it tends to remain at rest is called inertia of rest and if the ...

For an object moving along a straight path in an accelerated motion, it is not necessary that it always goes away from the earth.

Given, initial velocity = u, height = h and a = g. At the highest point, the final velocity becomes zero, i.e., v = 0. From the third equation of motion, V² = U² – 2gh 0 = u² – ...

In merry-go-round, the speed is constant but velocity is not constant, because its direction goes on changing i.e., there is acceleration in the circular motion. So, we can say that the boy is in accelerated motion.
