  2. Impulse (physics) - Wikipedia

    en.wikipedia.org/wiki/Impulse_(physics)

    v 2 is the final velocity of the object at the end of the time interval, and; v 1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (MLT −1) as momentum. In the International System of Units, these are kg⋅m/s = N⋅s. In English engineering units, they are slug⋅ft/s = lbf⋅s.

  3. Elastic collision - Wikipedia

    en.wikipedia.org/wiki/Elastic_collision

    v 1 (v A1 or v B1) is the initial velocity of the particle. If both masses are the same, we have a trivial solution: = =. This simply corresponds to the bodies exchanging their initial velocities with each other. [2]

  4. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    The initial velocity, v i, is the speed at which said object is launched from the point of origin. The initial angle , θ i , is the angle at which said object is released. The g is the respective gravitational pull on the object within a null-medium.

  5. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    where is the initial velocity, is the launch angle and is the acceleration due to gravity as a positive value. The expression can be obtained by evaluating the arc length integral for the height-distance parabola between the bounds initial and final displacement (i.e. between 0 and the horizontal range of the projectile) such that:

  6. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    Trajectory of a particle with initial position vector r 0 and velocity v 0, subject to constant acceleration a, all three quantities in any direction, and the position r(t) and velocity v(t) after time t. The initial position, initial velocity, and acceleration vectors need not be collinear, and the equations of motion take an almost identical ...

  7. Simple harmonic motion - Wikipedia

    en.wikipedia.org/wiki/Simple_harmonic_motion

    In the solution, c 1 and c 2 are two constants determined by the initial conditions (specifically, the initial position at time t = 0 is c 1, while the initial velocity is c 2 ω), and the origin is set to be the equilibrium position.

  8. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    If the cannonball is launched with a greater initial horizontal velocity, then it will travel farther before it hits the ground, but it will still hit the ground in the same amount of time. However, if the cannonball is launched with an even larger initial velocity, then the curvature of the Earth becomes significant: the ground itself will ...

  9. Coefficient of restitution - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_restitution

    The COR is a property of a pair of objects in a collision, not a single object. If a given object collides with two different objects, each collision has its own COR. When a single object is described as having a given coefficient of restitution, as if it were an intrinsic property without reference to a second object, some assumptions have been made – for example that the collision is with ...
