i need three different project topic in physics

a ball thrown with the speed of 100mls. altains a height of 150m! calculate a the time of flight b the angle of projection c the range

Sure! Here are three different project topics in physics:

1. Investigating the Magnus Effect: The Magnus effect is the phenomenon by which a spinning object experiences a sideways force. You could design an experiment to study this effect by experimenting with spinning objects, such as basketballs or cylinders, and measuring the resulting forces and trajectories. To get started, you can research the basic principles of the Magnus effect, gather necessary materials, and design an experiment setup that allows you to measure and analyze the forces and trajectories.

2. Exploring the Efficiency of Solar Cells: Solar cells are devices that convert sunlight into electricity. You could conduct a project to evaluate and compare the efficiency of different types of solar cells. Start by researching the factors affecting solar cell efficiency, different types of solar cells (e.g., silicon-based, thin-film, multi-junction), and methods to measure their efficiency. Then, design an experiment setup to expose different solar cells to varying light intensities, measure their electrical output, and analyze the results to determine their efficiency.

3. Investigating the Factors Affecting Pendulum Period: A pendulum is a simple harmonic oscillator that can oscillate back and forth. You can conduct a project to explore and analyze the factors affecting the period of a pendulum. Research the fundamental principles governing pendulum motion, including factors such as length, mass, amplitude, and gravity. Then, design an experiment using a pendulum with adjustable parameters, measure the period for different parameter values, and analyze the data to observe their effects.

Remember, these are just starting points for your projects. As you delve deeper into each topic, you will find more specific questions to answer and experiment design considerations to explore.
