SOMETHING THAT TENDS TO CAUSE A CHANGE IN MOTION. MEASURED IN METERS PER SECOND SQUARED
1 of 20
IMPULSE
THE EFFECT OF A FORCE ACTING OVER A PERIOD OF TIME.
2 of 20
VELOCITY
THE RATE OF CHANGE OF DISPLACEMENT OR DISPLACEMENT DIVIDED BY TIME, MEASURED IN METERS PER SECOND. DIRECTION IS IMPORTANT.
3 of 20
SPEED
THE RATE OF CHANGE OF DISTANCE - DIRECTION NOT IMPORTANT.
4 of 20
DISPLACEMENT
THE SHORTEST STRAIGHT-LINE MEASUREMENT BETWEEN TWO POINTS.
5 of 20
ACCELERATION
THE RATE OF CHANGE OF VELOCITY OR THE DIFFERENCE BETWEEN FINAL AND INITIAL VELOCITIES DIVIDED BY THE TIME TAKEN, MEASURED IN METERS PER SECOND SQUARED.
6 of 20
DECELERATION
A NEGATIVE CHANGE IN VELOCITY OVER TIME OR NEGATIVE ACCELERATION
7 of 20
VECTOR
A QUANTITY THAT HAS TWO DIMENSIONS, MAGNITUDE AND DIRECTION EG VELOCITY
8 of 20
SCALAR
A QUANTITY THAT HAS A SINGLE DIMENSION OR MAGNITUDE EG SPEED
9 of 20
AIR RESISTANCE
FRICTION BETWEEN A BODY AND AIR PARTICLES
10 of 20
GRAVITY
THE FORCE OF ATTRACTION BETWEEN TWO BODIES, FORCE PULLS OBJECT TOWARDS THE CENTRE OF THE EARTH.
11 of 20
INERTIA
THE RELUCTANCE TO CHANGE THE STATE OF MOTION (MEANS LAZINESS IN LATIN)
12 of 20
POSITIVE IMPULSE
AN IMPULSE THAT MOVES A BODY
13 of 20
NEGATIVE IMPULSE
A FORCE GENERATED WHEN ABSORBING BODY MOTION- LANDING
14 of 20
ZERO IMPULSE
NEGATIVE IMPULSE=POSITIVE IMPULSE SO THEREFORE THERE IS NO ACCELERATION OR DECELERATION- RUNNER IS AT CONSTANT VELOCITY FOR EXAMPLE.
15 of 20
MOMENTUM
THE QUANTITY OF MOTION OF A BODY (MASS X VELOCITY)
16 of 20
GROUND REACTION FORCE
THE EQUAL AND OPPOSITE FORCE GIVEN TO A PERFORMER WHO EXERTS A MUSCULAR FORCE IN TO THE GROUND
17 of 20
FOOTFALL
THE ACTION OF THE FOOT MAKING CONTACT WITH THE GROUND WHEN WALKING, RUNNING OR JUMPING.
18 of 20
AGONIST
MUSCLE OR MUSCLE GROUP WHOSE ACTION IS MAINLY RESPONSIBLE FR PRODUCING A GIVEN MOTION
19 of 20
ANTAGONIST
ACTS TO PRODUCE THE OPPOSITE ACTION OF THE PRIME MOVER
