Application of forces

HideShow resource information
Footfall
the action of the foot making contact with the ground when walking, running or jumping
1 of 23
Negative impulse
a force generated when absorbing body motion-landing
2 of 23
Positive impulse
an impulse that moves the body
3 of 23
Angular velocity
the rate of movement in rotation.
4 of 23
Angular acceleration
the amount of motion that the body has during rotation - angular velocity X momentum of inertia.
5 of 23
Angular momentum
the amount of motion that the body has during rotation - angular velocity X momentum of inertia.
6 of 23
Moment of inertia
the resistance of a body to a change of state when rotating.
7 of 23
Angular
a word used to describe the motion of a mass when it is rotating or spinning.
8 of 23
Moment
the turning effect produced by a force, measured in newton metres(Nm); also known as torque.
9 of 23
Moment arm
the perpendicular distance from the point of application of a force to the axis of rotation.
10 of 23
Resistance arm
the mass and the lever system from the mass to the fulcrum.
11 of 23
Effort arm
the part of the lever system from where the effort is applied to the fulcrum.
12 of 23
Perpendicular
at right angles to.
13 of 23
Principle of moments
for a body to be equilibrium (balance), the sum of the clockwise moments is equal to the sum of the anticlockwise moments about the fulcrum (pivot)
14 of 23
Angular movement
the movement of a body or mass around an axis- spinning, rotating, turning.
15 of 23
Conservation of angular movement
the principle that the angular momentum of an object reaimins constant as long as no external force (moment or torque) acts on that object.
16 of 23
Radian
one radian equals 57.3 degrees
17 of 23
Angle of release
the angle at which an object is released, measured from the horizontal.
18 of 23
Parabolic curve
the flight path of a projectile in the absence of air resistance.
19 of 23
Horizontal component
the horizontal motion of an object in a parabolic flight curve.
20 of 23
Vertical component
the upward motion of an object in a parabolic flight curve.
21 of 23
Height of release
the highest point above the ground that an object is released.
22 of 23
Velocity of release
the velocity of the object when it is released from the hand.
