shows that the motion is non uniform. The car is not travelling at a constant velocity as the graph is not a straight line. A straight line graph would indicate that the motion is uniform as the position increase is constant throughout. However‚ the graph of the toy car is a curve that becomes steeper as the time increases. This suggests that the motion increases more and more as time passes‚ showing that the velocity is increased each second. As the car is also moving in the positive direction‚

the graph on the right‚ line one is a line moving at a slower velocity compared to line 2 which is moving at a faster velocity in the same about time. There is a small error in this experiment‚ as you can see in the graph of the right‚ the velocity is not as constant. 5. What is the definition of velocity? Velocity is a vector quantity that has the same direction as the displacement. Displacement per unit time is called Velocity. 6. What did you have to do to

Acceleration = velocity/time = -10/5 = -2 m/s/s. (- sign means a deceleration from velocity of 10 to 0) Force = 1000 x -2 = -2000 Newtons (i.e. 2000N in opposite direction to motion) Multiple Choice Question 6.11 When you jump from an elevated position you usually bend your knees upon reaching the

Cart on an Incline Lab Kennedy Van Allen SPH 4U1 February 20‚ 2014 M. Reid Purpose: To determine both qualitative and quantitative properties of the motion of a cart on an inclined plane on position vs. time‚ velocity vs. time and acceleration vs. time graphs. Question: Which properties of the cart’s motion can be determined from examining each of the three graphs? Hypothesis: The predictions on the type of motion demonstrated by the cart-qualitatively- are shown below.

into the subtopics of kinematics and dynamics. Kinematics is concerned with the aspects of motion that exclude the forces that cause motion. In a manner of speaking‚ kinematics is focussed on the development of definitions: position‚ displacement‚ velocity‚ acceleration and on the relationships that exist between them. Dynamics widens the study of motion to include the concepts of force and energy. Definitions Position Kinematics begins with the idea of position. Suppose that we photograph an object

These particular materials reduce the mass of the plane and contribute to making the plane become airborne. For example‚ let’s say‚ a plane is accelerating at a speed of 7.1 m s-2 and its total mass is 1.15 x 105 kg‚ for us to figure out the relative force we need to use this formula‚ F = ma. So F = (2.26 x 105) x 7.1= 8.17 x 105 N. The previous formula is Newton’s Second Law of motion and is stated as ‘Force equals mass times acceleration’. As you can see there needs to be a great amount of
