Which of the following are true for projectile motion?

There is more then one



A. Projectile motion always involves motion in two dimensions.

B. Gravity is the only force acting on an object in projectile motion.

C. For an object to be in projectile motion, air resistance must be too small to matter.

D. Objects in projectile motion have only a horizontal acceleration.Which of the following are true for projectile motion?C,A,B

D- not true - projectiles do not have only horizontal accelerations because they accelerate in the y-dimension due to gravityWhich of the following are true for projectile motion?Well, when an object can be called a projectile, that means that it is in Free Fall(only gravity is effecting it).

So, B. is right.

Also, since only gravity is affecting it, then air resistance cannot be.

So, C. is also right.

D. cannot be right because that would be assuming that the object is not accelerating up or downwards, and we all know that gravity makes something accelerate, wether positively or negatively.

As for A., I beleive that it is correct, too.Which of the following are true for projectile motion?a, b, c
