What is projectie |
|
Answer» Projectile is a name given to the body which ones thrown into the space with some initial velocity. When a particle is thrown by making some angle near the earth surface then it moves in curved path the motion of particle is called projectile motion and particle is projectile Projectile is just a name in which object moves in 2 dimensions |

By the use of graph derive kinematics equation |
|
Answer» x = total area covered by object =>x=area of rectangle + area of triangle=> x=v0t+ 1/2 (v-v0)t=>x=v0t+1/2(at)t ....from 1...=> x=v0t +1/2 at^2 =>delta a =delta v/t=>da=dv/dt=> da=v-v0/t=> at=v-v0=>v=v0+at |

Explain how walking of a person can be example of resolution of vector |
| Answer» Yes, when a man walks, he pushes the ground with his foot. In return, an equal and opposite reaction act, on his foot. The reaction is resolved in two components : horizontal and vertical components. The horizontal component of the reaction helps the man to have forward while the vertical component balances the weight of the man. | |

What is a intrigation |
|
Answer» It is the reverse of differentiation.... Integration is the process of finding an anti-derivative of a given function f. ‘Integrate f’ means ‘find an anti-derivative of f’. Such an anti-derivative may be called an indefinite integral of f and be denoted by ∫f(x) dx If you know differentiation then it is it\'s inverse only so first go for differentiation in physics it is very easy just compromise of 4 to 5 formulas in which 2 are mostly used in physics or in maths |

Can the speed of an object change if its velocity is constant? |
| Answer» An object can accelerate while traveling at constant speed but not at constant velocity. ... On the other hand, a constant velocity means no change in velocity (both magnitude and direction), so in this case the acceleration must be zero (no acceleration). | |
| 9172. |
Can the speed of an object change if it\'s velocity is constant |
| Answer» No. Because when velocity is constant, then means zero accerleration is acting on the body. So, there is no question about change in speed. | |
