Newton’s Third Law of Motion states that ‘To every action there is an equal and opposite reaction’. It is a common observation that when we sit on a chair, our body exerts a downward force…

The second law states that the rate of change of momentum of a body, is directly proportional to the force applied and this change in momentum takes place in the direction of the applied force.…

The first law states that every body continues in its state of rest or of uniform motion along a straight line unless it is compelled by an external force to change that state. This law…

Example 1: At time t = 0, the displacement is x = 2.72 m, the velocity is v = —2.54 m/s, and the acceleration is a = —10.87 m/s2. a) Find the amplitude, phase, and…

Example 1: An object goes around a vertical circular track, as shown. Find the minimum speed of the object near the top of the loop, so that it does not loose contact with the track.…

In uniform circular motion, the object travels with constant speed v along a fixed circular trajectory with radius r. The speed and radius determine the period of the motion, i.e., the time to complete one…

Example 1: A projectile is launched with V0 = 19.2 m/s at angle θ0 = 38.7°. a) Does the projectile `clear’ a 3.0 m- high wall that is 30 m from the launch? b) How…

Example 1: Emmy starts at time t = 0 and drives along a straight path: she starts at point A, drives straight to point B, turns aorund and drives to point C. She ends up…
