1. A particle accelerates from rest with an acceleration of 8.0m/s2. Calculate its velocity after 150s. What kinematic formula must be used to solve this problem?
Answer:
multification for solving this formula
2. history of kinematics
"the branch of mechanics concerned with the motion of objects without reference to the forces that cause the motion." concept of Galileo
3. causes of kinematics
kinematics is the study of the motion of points,objects,and groups of objects without considering the couses of its motion
4. Kinematics Formula (Free Fall)
kinematics equation to describe the motion of an object in free fall is similar to any moving object
[tex]velocity - time : \\ vf = vi + at \\ \\ velocity - position : \\ {(vf)}^{2} = {(vi)}^{2} + 2ad \\ \\ position \: time : \\ d = (vi)t + \frac{1}{2} a {t}^{2} \\ also \: rewritten \: as \\ d = (vf)t - \frac{1}{2} a {t}^{2} \\ d = \frac{1}{2} (vf + vi)t \\ \\ where \\ vf = final \: velocity \\ vi = initial \: velocity \\ a = acceleration \\ t = time \\ d = distance \: or \: displacement[/tex]
since free-falling object is under the sole influence of gravity, such an object will experience a downward acceleration of 9.8 m/s^2
[tex]a = gravity = 9.8 \frac{m}{ {s}^{2} } [/tex]

7. How will you differentiate from Kinematics in one dimension to Kinematics in two or threedimensions?
Answer:
The difference is in Parallel Transport. A vector originally tangent to the line on which a motion is taking place will change its orientation accordingly, depending on the dimensions of the space on which this line lives in.
For example if the line is an 1-manifold the vector always stays parallel to the line, whereas if it is a 2-manifold and the line rests upon the surface of a sphere say, the vector changes the angle it makes with the tangent to the line if the line is not a geodesic, and so on for higher surfaces with dimensions greater than 2.

13. what is the relationship of kinematics to centripetal force?
Answer:
As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. ... As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.
14. How do the branches of Kinematics differ?
Both the branches of physics deals with the different forces acting upon an object. Kinematics describes the motion of the bodies and deals with finding out velocities or accelerations for various objects. Kinetics deals with the forces or torque applied on a body.

17. complete the table about kinematic projectile motion.
Answer:Properties of Projectile MotionProjectile motion is the motion of an object thrown (projected) into the air. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory. As an object travels through the air, it encounters a frictional force that slows its motion called air resistance. Air resistance does significantly alter trajectory motion, but due to the difficulty in calculation, it is ignored in introductory physics.

30. kinematics of projectile motion description
Answer:
Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.
