Projectiles, Part 2




Assuming that you can throw all objects at a speed of 3 m/s, what effect will a changing angle have on the distance a projectile travels?

What about a changing mass?

  1. a changing angle will make it go higher if the angle is larger but it will cover less ground...Changing the mass will have no effect unless you add in the air resistance factor...

  2. if you throw the ball straight at 3 ms and then throw it at a different angle the speed might change a bit

  3. the angle will change how far it goes, or how high it goes... the mass might affect the same things...

  4. The bigger the angle the higher the object goes but it goes a shorter distance.

  5. -For angle The higher the number the more angle it has and the higher it goes.

    -Changing the mass is and isnt that big of a deal for mass the more it weighs the more foce you have to use and if you dont have alot of mass you dont put as much force.

  6. if your changing mass it might not go as far if you making it heavier.. and if your making it lighter it would depend on like if it was windy or something?

  7. if you throw the ball at a bigger angle it will go higher.
    the mass will not mater

  8. changing the angle higher will make the ball go higher but cover less ground. Making the angle lower will make the ball go lower but cover more ground.

    changing the mass doesn't exactly make a difference..unless it is too heavy to lift or has too much air resistance

  9. will land in different spots father away same as if you change mass

  10. it would slow down after the ball reaches the surtant level of the hight the ball wants to go to.

  11. I think it will go a shorter distance

    It will go a shorter distance because there will be more gravity on the object

  12. The higher the angle the longer it will take to travel.

    The more mass the harder it will be to throw the ball but the travel time will be the same.

  13. The steeper the angle the higher the object will go, but it will also travel a lesser distance.
    The smaller the angle, the further nit will travel, but it will not go as high into the air

    No matter what the mass of an object it will still go at the same rate, its the shape that matters

  14. You would have to change the angle between 40 degrees and 60 degrees. Because if you go higher it will just go up but if lower it will just go at a straight line. The mass doesn't really affect it.

  15. mass has a effect on how long an object will go when thrown.
    different objects will have different masses which will make a difference in how long it goes.

  16. The higher the angle the shorter distance the object will go. The lower the angle the longer distance the object will go.
    The mass of the ball will decrease the speed at which the object can be projected.

  17. a change in the angle will make it go higher but will cover less ground. changing the mass will have no effect unless u add air resistance.

  18. A larger mass wil shorten the distance you can throw an obect, and a higher andgle, to a point will alow it too go further too, but when you get close to throwing it straight up, it doesnt go as far.
