Curvilinear motion

Types of acceleration	Acceleration detection	Acceleration formula
1. Tangential acceleration	This acceleration is directed tangentially to the trajectory of motion
2. Centripetal acceleration	This acceleration is directed to the center of the circle
3. Complex acceleration	This is the vector sum of tangential and centripetal accelerations

2.Read each statement. Set TRUE (T) if the statement is true or FALSE (F) if it is not

а) Tangential acceleration - This acceleration is directed tangentially to the trajectory of motion

b) Centripetal acceleration - This acceleration is directed tangentially to the trajectory of motion

c) Complex acceleration - This acceleration is directed to the center of the circle

d) Centripetal acceleration - This acceleration is directed to the center of the circle

e) Tangential acceleration - This acceleration is directed tangentially to the trajectory of motion

f) Complex acceleration - This acceleration is directed tangentially to the trajectory of motion

g) Tangential acceleration - This is the vector sum of tangential and centripetal accelerations

h) Centripetal acceleration - This is the vector sum of tangential and centripetal accelerations

i) Complex acceleration - This is the vector sum of tangential and centripetal accelerations

Solved task:

The body moves in a circle at a speed of 5 m/s. Find the radius of curvature of the trajectory, if the centripetal acceleration of the body is 4 m/s².
