Tool to measure force
What is forcemeter?
Distance moved/Time taken
What is average speed?
If object A exerts a force on object B, then object B will exert an equal but opposite force on object A.
What is Newton's third law?/ What is action reaction?
Gaining velocity at a steady rate
What is uniform acceleration?
The forward force from an aircraft engine
What is thrust?
Time intervals of many seconds or minutes can be measured by using a .....................
What is Stopclock or stopwatch?
What is impulse? / What is change in momentum?
When two or more objects act on each other, their total momentum remains constant, provided no external forces are acting.
What is law of conservation of momentum?
The friction type that materials have when they are moving. It causes heat.
What is Dynamic friction?
The force in a stretched material
What is tension?
A quick method of finding density of a liquid it to use a small float. It is used to find relative density
What is hydrometer?
MassxAcceleration
What is resultant force?
For a fixed mass of gas at a constant temperature, the pressure is inversely proportional to the volume
What is Boyle's law?
Material which can go back to its original state after being stretched
What is elastic?
The force that opposes the motion of one material sliding past another.
What is friction?
Instrument that measures atmospheric pressure
What is barometer?
What is momentum?
If no external force is acting on it, an object will
-if stationary, remain stationary
-if moving, keep moving at a steady speed in a straight line
What is inertia?/What is Newton's first law?
Gaining speed in a nonconstant rate
What is non-uniform acceleration?
What is weight?
A tool that measures pressure difference.
Forcexperpendicular distance from the point
What is moment?
What is hooke's law?
-All masses attract each other
-The greater the masses, the stronger the force.
-The closer the masses, the stronger the force.
What is gravitational force?
The upward force from a liquid( or gas) that makes some things float
What is upthrust?
