Question: I need a step by step experiment for a science fair project.?

Answer: You have to find something you like to do first so that you can really get into the assignment. It’s hard to pick a project out of the air.

Question: How does mass affect the speed of different weighing balls?

I’m doing a science experiment. can someone help me that if u have 3 balls that weigh each differently, ( none is heavy, one weighs medium and one is light weight), and i pushed them all with the same force, and my hypothesis is that the heavy one is slowest, but it was really the opposite. so, to write a conclusion , how does mass affect the speed of the balls.
One ball is heavy, sorry for my bad typing error

Answer: You may have heard of or seen this physics formula at some point in your life: F = m*a Force equals mass times acceleration.

You have three balls of different masses. Let’s says for example that the balls are 10 kg, 55 kg, and 100 kg, respectively. Let’s also say that you push each ball with the same amount of force, let’s say for example, 50 N. Here’s how they should accelerate:

F = m*a F=m*a F = m*a
a = F/m a = F/m a = F/m
a = 50/10 a = 50/55 a = 50/100
a = 5 m/s^2 a = 0.91 m/s^2 a = 0.50 m/s^2

The masses of the balls should have no effect on their speed. The masses, however, DO affect the rate at which the speed changes, or the acceleration. The lightest ball should have accelerated the fastest, and the heaviest ball should have accelerated the slowest. Since the mass doesn’t affect speed, the acceleration is the only thing that would seem to make one ball go faster or farther than the others. Also, some people may argue that, since the heaviest ball has a greater mass, it will also have the most kinetic energy. That doesn’t matter in this case. Also, make sure all the balls have the exact same texture. Otherwise, you may have to consider friction as another variable.

Question: Help me please, I need a creative title for my Science Project!?

We have to use a tri-fold display board and my experiment is how soap in water affects the growth rate of a plant.
I want a short and sweet title that will grab someone’s attention.

ie: my friend is doing a science experiment on which plants will grow taller listening to which kind of music and they titled it “Musical Plants”.

Answer: “Plants Sipping Soap”

Good luck!
