Projectiles do not move horizontally
False, they move horizontally as well as vertically
What's the Y velocity at half time? (shakira shakira)
0
What is perpendicular to velocity in a centripetal force problem?
Acceleration
Centripetal Force is the net force in circular motion
True centripetal force is just the net force
Circular motion does not involve the circumference of a circle
False - circular motion is motion along the circumference
A projectile is an object in which only gravity acts upon it
True a projectile is an object with gravity acting on it
Centripetal means center seeking.
true centripetal does mean center seeking
What are the main forces in Circular Motion?
Friction, Tension, Gravity, Normal Force, and combinations
What is the shape of motion for projectiles?
Parabola
at the maximum height of a projectile, the velocity is equal to zero.
true velocity is zero at max height
Velocity is constant when an object is undergoing centripetal acceleration.
False - speed is constant
what is a projectile
anything that is propelled through the air
The vertical component of a projectile's velocity is constant
False - it depends on gravity
A projectile is a free-falling object
True free falling objects are projectiles

A car moves around a circular path of a constant radius at a constant velocity
False car would have constant speed not velocity
what is circular motion?
a movement of an object along the circumference of a circle or rotation along a circular path(Luke Brozo)
A projectile's motion horizontally is one of constant acceleration
False: a projectile's motion horizontally is one of constant velocity
Time is what connects the vertical and horizontal motion
True time is the connecting force
Projectiles have a horizontal acceleration
False projectiles have vertical acceleration
When an object is moving in a circular path, the object's velocity is tangential
True - the motion is tangential
The curve-shaped path of a projectile
Parabola
