Observations • The more force we apply on an object‚ the faster an object goes. • The more mass an object has‚ the more difficult it is to change its state of motion. • Though the second attempt has more mass‚ it still has the same acceleration as the first one. • Air resistance from ceiling fan also affects the force

Motion Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air‚ near the surface of the earth‚ at the very top of its flight? Answer : The acceleration is downwards at 9. 8 m/s 2 . The only force acting on

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate

a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences in the acceleration to determine how the ring and the disk resist rotational movement. Afterward we will compare how the radius of the masses and the torque(force) applied relate to the angular acceleration. We will achieve a predictable force by using g=gravity=9.8 for this acceleration. Theory: In this experiment we will measure the inertia

(Term I) 10a Gravitation IMPORTANTIMPORTANT NOTES NOTES IMPORTANT NOTES 7. Acceleration due to gravity of the Earth : The acceleration with which the bodies fall towards the earth is called acceleration due to gravity. Its average value is 9.81 ms–2. 8. Variation of acceleration due to gravity. (i) Acceleration due to gravity changes with the change in distance from the centre of the earth. (ii) Acceleration due to gravity is maximum at the poles of the earth. Its value decreases as we move
