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
