The football was heavier in 1970.
A football with no air is heavier than a football with full air because the air adds buoyancy and makes it lighter.
mo its not the Baseball is hevier
An old football has a different shape then a new one and it is often heavier and made of actual pigskin.
Because the heavier football player has a much higher momentum which is product of mass and velocity. To cancel the momentum of a heavier football player one must achieve the same momentum at impact. A lighter player can only do that by increasing his velocity.Momentum = mass x velocityIf a football player weighed 100 Kg and was traveling at 5 m/s (11 miles per hour). A 50 Kg person would have to impact the heavier football player at a speed of 10 m/s (22 miles per hour) to cancel the inertia of the heavier football player.As the heavier football player goes faster it becomes increasingly difficult to stop them. You can also take several lighter players by combining their mass to stop the forward momentum of the heavier football player.
A football coach might use a fast runner because if he wants to get a touchdown on the last four second or so the fast runner might make it on time and then they might win.
It depends on what you are good at. If you have exceptional balance, and are a light person, football will be harder. If you are a heavier, strong, person who does not have good balance, you will find ballet is harder.
No the weight of the ball will slow it down then gravity will take hold and it will fall to the ground
yes
Obviously. Liquid has mass, so yes it makes it heavier.
A Gaelic ball is slight smaller and also heavier. Dont try to head it.
Put salsa in it
