1 ) 0 Aim:

The aim of this kind of experiment is to determine how the height of a horizontally launched projectile affects the projectiles selection.

2 . 0 Theory:

Galileo showed a great appreciation for the proper romance between mathematics, theoretical physics, and fresh physics.

Galileo discovered that a parabola was the theoretically best trajectory of your accelerated charge in the a shortage of friction and other disturbances. Galileo agreed that we now have limits to the validity of this theory and noted a projectile flight which was nearby the size The planet could not become presented like a parabola but he believed that miles reached while using artillery employed in his working day would just have a slight impact to the parabolic representation. Applying Galileo's theory on projectile motion, we can deduce that projectile movement is made up of two motions. a) Horizontal aspect which is continuous velocity

b) Vertical component which is constant acceleration.

In class, a computer sim was used to reply to questions and indicate any kind of relationships between the change in selected variables and just how that influenced different effects. Since the mass and angle of desire were regular, there was simply no changes in info gathered that was impacted by stated variables. Through the computerized simulations, the class acquired gathered that as the peak of the equipment changed time of air travel increased and thus did the horizontal range.

This kind of graph shows the parabolic relationship between change in your initial height and just how it affects the side to side range. The speed of the ball as it leaves the equipment can be determined by the preservation of energy equation. Due to the metal balls spherical shape, rotating motion must also be taken into mind so the equation changes. several. 0 Materials/Equipment:

Metal BallPlastic tube

Rack of sandRuler (30cm and 1m)

Producing utensils (pencils)

Tape measureSticky Tape

5. 0 Risk Assessment

Risk

Solution

Stepping on the ball

Supply a clear way for the ball to stay on using a closed finishing which prevents the ball being moved on. Slipping on loose sand

Brush and collect any loose sand because the test is done. Collision with flying charge

Performing the experiment with the queue of output aimed aside of class mates will lessen the chance of injury or being captured in crossfire

5. zero Method

1 . Position the tube on the edge of table.

installment payments on your Measure the elevation of the apparatus from the ground up to the exit point. 3. Identify the position on the tube from which the ball will be unveiled. 4. Relieve the ball from this placement and note the approx . point of landing; obtain the ball. 5. You can put tray of sand on the approximate getting point. Make sure the surface of the crushed stone is smooth. 6. Launch the ball and get it from your tray of sand. Evaluate how far the projectile travelled. 7. Soft over the area of the yellow sand.

8. Do it again steps 4-7 changing the height of the equipment after every 5th measurement.
