A combination of both linear and angular motion, when an object and its mass is moving in the same direction because of the torque produced through an axis of r
What is torque?
The force (power) that causes rotation.
Newton's 3rd Law of motion is:
Law of action and reaction
Something at rest will stay at rest unless acted upon by a ______
Force
List 2 factors that affect stability:
Mass of the object, area of the base of support, height of the objects center of gravity about the base, relationship of the line of gravity to the edge of base
What is moment of inertia?
The closer the mass is distributed to the axis of rotation, the easier it is to rotate.
Three factors that impact the trajectory (flight path) of an object are:
Angle of release, height of release, velocity at release
An internal force is
muscle contractions
Momentum is
An objects tendency to keep moving
Formula for momentum is
Mass x Velocity
Velocity is
The rate at which an object moves from one location to another
What is gravity?
A force that pulls objects towards the earth
Force summation is
The combination of forces from different body parts to work together at the same time
Inertia is
an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a force
A force will _____ or _______
Push, Pull
Projectile motion is:
The movement of an object through the air
What is angular motion?
When a body or object turns about an axis of rotation
The four resistive forces are
Friction, gravity, drag and fluid resistance
For every action there is a
equal and opposite reaction
Formula for velocity is
displacement / time
Two factors that need to be controlled for any angular motion are:
Amount of force applied and length of the levers involved
Newton's 1st Law of motion is:
Law of Inertia
Displacement is
The difference between the initial and final position of an object
What is linear motion?
When an object and its mass move in the same direction and the same time
