N down. The force she is putting down on the bar measures to 20 N. The bar is supporting the weight of the gymnast. Its force is 35 N in the upward direction. Friction is another factor, with the force of 5 N up. A gymnast needs friction in order to be able to swing and avoid slipping. Both directions of force even out to 40 N on each side. When you set up an equation and subtract the two directions, the amount of force equals out to 0 N. This ending sum of zero means that the forces are balanced

251 Force Activity 1-1: Introduction to Force Procedure: 1. Place one end of a rubber band around the vertical rod on your table. 2. Stretch the rubber band to a length of 10cm beyond its unstretched length, L0. [pic] 3. Place two rubber bands around the rod and stretch them together a length of 10cm Question 1-1: How does the combined force of two rubber bands compare to the force of just one rubber band? 1. Repeat with 3, 4 5 rubber bands. Activity 1-2: Measuring Force with

valid because if a force is a push or a pull, when an unbalanced force is applied to an object, the object will move in the direction of the stronger force, and if a force is a push or a pull, when a balanced force is applied to an object, the object will not move. Evidence that supports my first claim are that in task 3, when I put a larger sized person on the left, and a smaller sized person on the right at the same distance from the cart, the person on the left had more force, which resulted in

use of force by law enforcement officers is described by the Internal Association of Chiefs of Police as the “amount of effort required by police to compel compliance by an unwilling subject” (National Institute of Justice, 2016). The amount of force used by the law enforcement officer is situational based dependent the officer’s perception and the subject’s actions (National Institute of Justice, 2016). When a law enforcement officer uses force, they should only use the amount of force necessary

the one in control of the situation. A lot of the times an officer is alone, and needs to be proficient with his or her ability to defend themselves and the general public. Not every situation calls for a use of force incident, and not every use of force incident should be a deadly force incident. That is why the baton, OC spray, taser, and hands on techniques in order to gain compliance are very important to know and have.

The Basic Forces in Human Development: The Biopsychosocial Framework is a critical framework that truly affects our growth. From the interaction of these four forces, scientists use this model as an indication to help explain the development of each individual. Specific interactions between each of these forces makes each individual special and unlike anyone else. The Biopsychosocial Framework consists of four forces including biological forces, psychological forces, sociocultural forces, and life-cycle

cover kinetic energy, gravity,velocity, and force of impact. Even if we know the process of conservation of energy to an object that is falling allowing us to predict its impact velocity, as well as the kinetic energy. However we cannot predict the impact force without knowing how far it will travel after impact. When you find the product of average force, and time that is exerted is called impulse of force. “From Newton’s second law the impulse of force can be extracted and found to be equal to
