An object or living organism that is stationary(not moving) for example the car is stopped at the top of the hill
Which ramp is going to make the ball travel down faster?
The 2nd ramp because it is steeper and would give the ball a faster push caused by gravity than the 1st ramp.
It can help you feel better about your self and body
Answer:
Tangential acceleration is in the direction of velocity - along the circumference of a circle if the object is undergoing circular motion
a = (V2 - V1) / T
Radial acceleration is perpendicular to the direction of motion if the object is not moving in a straight line (perhaps along the circumference of a circle)
a = m V^2 / R = m ω^2 R where R is the radius vector of the velocity - note that the Radius vector is directed from the center of motion to the object and for circular motion would be constant in magnitude but not in direction
