    B How do helmets help prevent injury to the head?

    My essay question is "How has science been applied to contact sports equipment to increase safety?" and I am focusing on the equipments in american football and the science applied to these equipment to increase safety and prevent injuries.

    B How do helmets help prevent injury to the head?

    Hi. So I've got an essay I have to write on sports equipment and how they increase safety. I know that in football, equipment to increase safety includes helmets, shoulder pads or paddings and cleats. Unfortunately, I have no idea how each of those equipment work to increase safety. Okay, let's...

    Relationship between mass and acceleration

    Right. So... The mass of the pendulum bob does not affect the oscillation time of a simple pendulum. This is because the force due to gravity acting on the pendulum bob causing its movement (downward acceleration of falling object) is proportional to the mass. Hence, the acceleration of the...

    Relationship between mass and acceleration

    Ah okay thanks a lot! Just a dumb question here. So the force in F=ma when considering a free-falling object is weight right?

    Relationship between mass and acceleration

    Oh so basically what you're saying is similar to like when a = F/m, where the mass is doubled, the force will be doubled and hence they will cancel out so the acceleration remains the same and from what you said, m = 2F/2g (Oh and another question : Is there a scientific theory behind why force...

    Relationship between mass and acceleration

    Thanks but wouldn't what you said mean that if the mass increases, the gravitational force increases and hence the acceleration increases? If so isn't it opposite to what I'm conveying in my conclusion? Sorry I am not quite sure but thanks.

    Relationship between mass and acceleration

    Hi. I am currently working on an assessed science experiment write-up. The experiment is about whether or not if mass of a pendulum bob affect the oscillation time for a simple pendulum. Obviously, the answer is no but I am struggling to write a concise and accurate explanation to why this is. I...
