• ## How to Design a Parachute

If acceleration is constant uniform , the following equations can be used Projectile motion An object is said to undergo projectile motion when it follows a curved path due to the influence of gravity. If we assume air resistance to be negligible in a projectile motion: The horizontal component of velocity is constant The vertical component of velocity accelerates downwards at 9.

For example: If you jump out of a plane and undergo free-falling, you will feel an upward force exerted on you by the surrounding air due to air resistance. As you fall faster and faster due to gravity, this upward force exerted by air becomes greater and greater until it balances your weight.

At this point, the net force acting on you becomes zero, and you no longer accelerate. This specific velocity at which you stop accelerating during a free-fall is called the terminal velocity. The unit of force is newton N. Objects are represented as a point mass to enable the representation for forces as arrows in free-body diagrams. Free-body diagrams On a free body diagram, forces acting on an object are represented as arrows which stem from a point mass.

The length and direction of the arrows corresponds to the magnitude and the direction of the forces acting on the body of interest. Determining the resultant force 1. Resolve all acting forces into horizontal and vertical components 2.

Add up the horizontal components 3. Add up the vertical components 4. Combine the sum of horizontal components and the sum of vertical components Translational equilibrium A body is said to be in translational equilibrium if it the net force acting on the body is zero. This means the body is either at rest or travels at constant velocity.

This pair of forces is called an action-reaction pair, which must act on two different bodies. Solid friction Friction is a non conservative force which opposes motion. If there is no motion, then there will be no force caused by friction. For two solid surfaces moving over each other, the friction will be affected by the nature roughness etc of the two surfaces.

However, the surface area and velocity of the object does not affect the friction. There are also two types of friction for solid surfaces: static friction and kinetic friction.

Static friction is that which stops objects from beginning to move. Kinetic friction is that which slows objects down when they are moving. Static friction is always larger than kinetic friction. The work done W by a force F on an object is given by the equation In a force-displacement graph, work done is the area under the curve.

Principle of conservation of energy Energy can neither be created nor destroyed; it can only be changed from one form to another. For example: An electrical heater transforms electrical energy to thermal energy.

A falling object transforms potential energy to kinetic energy. Total energy of an isolated body remains constant. The change of momentum of an object is called impulse. Conservation of linear momentum The law of conservation of linear momentum states that the sum of initial momentum is equal to the sum of final momentum in a closed system and can be given by the equation Elastic collisions, inelastic collisions and explosions Type.

## Sample Physics IA ideas and questions

The physics 1 course is 3 Introduction credits and meets 3 hours per week. In addition, there is a Many colleges and universities are struggling to raise optional 1 -credit three-hour per-week laboratory course.

Each graduation rates, as the value of an undergraduate degree is physics 1 lecture section offers one optional associated being reassessed. All instructors use the department recommended majors, many of which will need introductory physics. If text, Young and Freedman, University Physics [8]. We need course.

The larger the DFW rates, the more students switch to stop thinking of these courses as a killer courses and into the parachute course. Or to paraphrase directly for the parachute course to take it as a physics prep Redish and Steen, we need to make these courses more of course. This stopped when both the College of Engineering the pump than a filter [1].

A parachute course is solving strategy [9]. The purpose of this physics 1 course. References based instruction based on Modeling Instruction mechanics 2.

Young and R. Freedman, University Physics Princeton Reviews. Many students are on took the parachute class and retook physics 1 and students [10] Modeling Instruction curriculum materials are available from scholarship, most provided by the state lottery scholarship who retook physics 1 without taking the parachute class.

The the American Modeling Teachers Association website with program. This course is average grade in retaking physics 1 between those who taught by a senior graduate students who had been a teaching completed the parachute course with a grade of B or better and assistant for Saul twice before. No data was available for those who did not take the parachute class.
