What is Newtons First law of motion?!
. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
100
Define the term density?
mass per unit volume
100
What is acceleration?
change in velocity in unit time
100
What is a vector?
magnitude and direction
100
what is hook law?
force is directly proportional to the extension provided that the elastic limit has not been exceeded.
200
What is Newtons Second Law of Motion?
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
200
What is the unit of volume?
meter cube
200
What is the unit for velocity?
ms-1
200
what is a scalar
only magnitude
200
if the extension was 34m and then 209m what is the extension?
175m
300
What is Newtons Third Law of Motion?!
For every action there is an equal and opposite reaction.
300
What is the density if the mass is 34 kg and the volume is 67 meters cube?
0.507 kgm-3
300
What is the time if the acceleration is 89 ms-2 and the change in velocity 78 ms-1?
0.87 s
300
Name 3 scalar qualities.
distance, speed volume mass time
300
if K is 34Nm-1 what is the force cause by the extension 2m
68N.
400
What is the definition of, force?
is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

Weight is 34 on the moon with g 1.4 Nkg-1 what is the weight on earth?
242 N
400
How speed different from velocity?
speed is a scalar and velocity is a vector.
400
Name 3 types of vectors?
displacement, velocity, acceleration and force
400
What is the extension of a spring in space if the force is 2333N
0

What is Mass?
the amount of matter, that there is in something.
500
What will be the mass of a ball in space if the mass is 2 times the mass of 50 kg
100 kg
500
Time in minutes if the velocity is 4.5 ms-1 and the displacement 350 m?
1.3 minutes
