Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П.

This is an F=ma questions. Remember that force and acceleration are vectors. (That's what the boldface font means.) 1) A 14kg object accelerates at (2,4) m/s2. Calculate the magnitude of the force on the object, in Newtons. 2) Calculate the mass if F = (200, 300) N and a = (0.9, 0.3) m/s2. Enter 0 if there exists no answer.

Analyzing Forces: Using Newton's 2nd Law A fireman has a mass of 75 kg. When the bell in the firehouse starts ringing, he slides down the pole with an acceleration of 3 m/s². What is the total force of friction acting on his body? 1. Identify the problem: What quantity are you being asked to find? What units will this answer be in? 2. Visualize and then sketch the problem. Draw arrows to illustrate the direction of the two forces acting on the fireman. Label these two forces by name. Do not use numbers yet. 3. These two forces act in opposite (+/-) directions and they will partially cancel. Assign the + value to the stronger force. The sum of these two forces is called the Net Force and it is the force which will actually move the fireman. Fill in the names of these two forces in the equation template below. (Hint: Remember that mass and weight are not the same.) Do not use numerical values yet: Net Force = + 4. Newton's 2nd Law gives us another equation for calculating Net Force: Net…
