Gravity
With audio from Mr D :)
Terms in this set (21)
average acceleration
change in velocity / time, V1-V0 / t or ΔV/t Unit = m/s²
average speed
distance / time, d/t. Unit = m/s
centripetal force
A net inward force exerted on a body in circular motion
circular motion
movement in the shape of a circle or ring
deceleration
a negative acceleration
displacement
the shortest distance from the initial to the final position of something
distance-time graph
Gradient of this graph = speed (velocity) =y/x - distance m / time s
force
mass x acceleration. F=ma. Unit= N. A dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion.
gravitational acceleration
the acceleration for any object moving under the sole influence of gravity
gravity
an attractive force between particles with mass
mass
a physical quantity expressing the amount of matter in a body
motion graph
a graph which represents the motion of an object
newton
the SI unit of force, equal to the force that produces an acceleration of one meter per second per second on a mass of one kilogram. (1kg/m/s² =1N)
Newton's First Law of Motion
A body remains at rest or in motion with a constant velocity unless acted upon by an external force.
orbit
the path followed by an object revolving around another object
speed
a scalar measure of the rate of movement of a body expressed either as the distance travelled divided by the time taken ( average ______) or the rate of change of position with respect to time at a particular point ( instantaneous _____ ). (m/s)
speed-time graph
Gradient of this graph is numerically equal to the acceleration. In this graph the area under the line is numerically equal to the distance travelled.
steady acceleration
uniform acceleration
terminal velocity
the velocity at which a falling body moves through a medium, as air, when the force of resistance of the medium is equal in magnitude and opposite in direction to the force of gravity.
velocity
ratio of change of position to time interval over which change takes place m/s 90° (=East) - a vector quantity
weight
mass x gravitational acceleration. W=mg. Unit= N.
