Two angles of projection for the same range
Horizontal range is give by This shows that there are two angles of projection for the same horizontal range i.e., J and (90 o - J ) with the horizontal. The projectile will cover the same horizontal range whether it is thrown at an angle (90 0 ..
Horizontal projectile
Substituting for t from the above equation in equation (2) we have, is a constant for a projectile projected upwards with a definite velocity v and at a place with a definite value of 'g'. Equation (3) is a second-degree equation in x, a first-degree equation in y and is the equation of a..
Horizontal projectile
If a body is projected horizontally from a certain height with a certain velocity, then the body is called a horizontal projectil..
Falling Objects and Acceleration due to Gravity
We know that whenever an object is dropped from a height, it falls towards the Earth. Similarly, when an object is projected vertically upwards, it goes up but after attaining a certain height, it starts falling down. It is the force of gravitation which pulls the object towards the..
Phasors
Phasors - Phasors are vectors, which rotate around an origin with a angular speed They have the following properties. (i) Phasors rotate clockwise about the origin with angular speed equal to the angular frequency of current and voltage. (ii) The length of the phasors represent the amplitude of the..
vertical and horizontal motions of a body
horizantal range of a projectile When the card is flicked with the finger the coin placed over it falls in the glass But the horizontal distance travelled by a projectile depends upon its velocity in the horizontal direction. The horizontal distance travelled by a projectile depends upon its velocity in the horizontal direction Th..
Horizontal range
It is the total horizontal distance from the point of projection to the point where the projectile returns back to the plane of projection. It is denoted by R. To calculate the horizontal range, we need to consider the horizontal motion of the uniform velocity vcos q , in..
Maximum Height
Maximum Height - Maximum height is denoted by the letter h m a x or H. It is also known as the vertical range. It is the maximum height to which a projectile rises above the horizontal plane of projection. In order to calculate the maximum height H, we make use of the fact that the veloci..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
