For example at car turning around a circular curve will stay at 12 m/s throughout the entire turn (provided the driver does not brake). The direction of the velocity vector is changing. A force is required in uniform

AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

Centrifugal force Centrifugal force (from Latin centrum‚ meaning "center"‚ and fugere‚ meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body’s path is continually redirected. In Newtonian mechanics‚ the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame‚ and a reaction force corresponding

Newton’s laws of motion Newton’s laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries‚ and can be summarized as follows: 1- The first law states that an object continues in its state of rest or uniform motion in a straight line unless compelled by an external unbalanced force. Since law

three major physics concepts: force‚ acceleration and velocity; many of which involve elastic propulsion and/or projectile motion. Various types of sporting equipment are constructed with springs and elastics‚ in order to absorb a force or apply a force to another object. In the context of this investigation‚ the spring is utilised to propel an object. According to Hooke’s law‚ F = -kx‚ the distance‚ x‚ that a spring is contracted or extended is proportional to the net force being exerted. Springs create

Good morning/ afternoon everyone First of all‚ thank you for inviting me to this exhibition of Poetry in Motion. I was inspired to create my work based on the poem called This Man‚ by the Solomon Islands poet‚ Celo Kulagoe. This poem is a critique of the all-encompassing power of money‚ which can dictate to presidents and prime ministers alike and can ruin those with few resources. This resonates with the current issue of Coal Seam Gas mining and its wealthy supporters‚ while the dangers to the

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre
