Ch. 7 Forces and Motion in Two Dimensions
... – Relate the height, time in the air, and the initial velocity of a projectile using its vertical motion, then determine the range. – Explain how the shape of the trajectory of a moving object depends upon the frame of reference from which it is observed. ...

المحاضرة الثالثة Circular Motion
... If the acceleration ac is not perpendicular to the path, there would be a component parallel to the path and also the velocity and lead to a change in the speed of the particle and this is inconsist with uniform circular motion. To derive the equation of acceleration of circular path consider th ...

Introduction to Forces Guided Notes
... In 17th c. ____________________________ also theorized that force is NOT needed to keep an object in the motion (straight-line, constant speed). Instead, he believed forces change motion. Every object resists change to its state of motion/velocity. To change it, the force must act on it. We call thi ...

... A car drives past point x=0 at time t=0 at a constant speed of 50 km/hr. Shortly after it accelerates rapidly to 100 km/hr at t1. It holds this speed until a rabbit runs onto the road at t2 when the car comes to a screeching stop. Which of the curves shown above best represents the car’s i) velocity ...

... a. How high does it climb ? We know vo = 10m/s and v = 0 v = vo –g t or 0 = 10 m/s – (10m/s2) t or t = 1 sec But x = vot – (1/2)gt2 = x = (10m/s)(1s) – (1/2)(-10m/s2)(1s)2 or x = 5 meters How fast does it come back at you? (discussed in class) ...

2. Laws of Motion
... What is Newton’s second law? If the resultant force acting on an object is not zero, all the forces are said to be unbalanced. This forms the basis of Newton’s second law of motion, which states: If the forces on an object are unbalanced, two things about the object can change: the speed of the o ...
