Motion Activity 4.1 Direction: Modified true or false. Write True if the statement is correct, if not, underline the words which make is the statement incorrect. Write your answer on the space provided. 1. In figure A, If the motor engine (force applied) was increased, there would be greater amount of force applied to the jeepney; therefore, it will move slower. 2. In this case, the acceleration of the jeepney depends on the amount of force applied. Hence, acceleration is indirectly proportional to force. 3. Suppose we apply the same amount of force in Figure A but increase the mass of the jeepney by placing boxes on it. The acceleration of the truck will increase. 4. It illustrates that the acceleration is directly proportional to the mass of the load if the force applied remain constant. 5. As the mass of the load increase, acceleration also increases. Activity 4.2 Direction: Classify the following newton's laws of motion if it is inertia, acceleration, or interaction. Write your answer on the space provided. 1. For every action, there is an equal or opposite reaction. 2. A body at rest will remain at rest and a body in motion will continue to move unless acted upon by a net force. 3. Applied Force is inversely proportional to mass of the load. 4. There is equal force acting on two different bodies. 5. Object at respite or in activity. Distance and Displacement Activity 5.1 Direction: Write DT for distance and DP for displacement. 1. The length traveled by a moving body. 2. It gives the extent of the length traveled but not the track. 3. It has a specified path. 4. It has both route and scale. 5. It is a scalar quantity. 6. It is a vector capacity. 7. It has a point of reference and a specified direction. 8. It gives the magnitude of the duration traveled and course.9. It changes in position with respect to a reference point. 10. Its mathematical computation depends on its direction
