What is -9.8m/s2
Define 'Projectile'
What is ANY OBJECT that is thrown, launched, or otherwise placed into the air and only affected by the force of gravity?
Can you have acceleration when moving at a constant velocity? Explain why or why not.
Yes. If you are changing direction.
As objects fall toward Earth's surface, their velocity.......
Increases
What is true about the horizontal acceleration of a projectile?
It's 0 m/s^2.
Newtons
What is the SI unit for Force?
John travels 30m in 2s. Calculate his speed.
What is 15m/s?
An object falls from the sky for 5 seconds. What is the velocity at that point?
*Hint: You may round.
What is 50 m/s
What is true about the horizontal velocities of a projectile moving through the air?
Horizontal velocities are CONSTANT
Which is faster:
5 m/s or -10 m/s
What is -10 m/s
If an object is dropped, the initial velocity is _______
The angle that will produce the same range, as a projectile launched at 30 degrees, provided they have the same initial speed.
What is 60 degrees?
Meters per second squared
What is Acceleration?
If an object has a velocity of -13 m/s, what must the object be doing?
What is 'moving to the left'?
The acceleration acting on all free fall objects (no matter if they are dropped or thrown) is....
