20 examples of vector quantity. The calculation of acceleration due to gravity and force and the different between mass and weight and four equation of motion and the types of motion and the explanation of motion and the definition
Answers
Answer:
1) Vector Quantities Examples
Impulse
Force
Momentum
Velocity
Acceleration
Displacement
Angle
Alternating Current
Torque Of Couple
Weight
Thrust
Electric Field Strength
Magnetic Field Strength
Gravitation
Angular Velocity
Angular Momentum
Centripetal Force
Drag Force
Frictional Force
Tension
2) Formula of Acceleration due to Gravity Force acting on a body due to gravity is given by, f = mg Where f is the force acting on the body, g is the acceleration due to gravity, m is mass of the body. According to the universal law of gravitation, f = GmM/(r+h) 2
3) Difference between mass and weight
Weight is depending on gravity but Mass isn’t depending on gravity.
Weight may vary from place to place but Mass is constant.
Weight produce the motion but mass resist the motion or acceleration.
Weight is measured by spring balance but Mass is measured by a physical balance.
The unit of weight is N but the unit of mass in kg
4) four equation of motion are
v=u+at
S=(u+v)/2t
S=ut+1/2 at^2
V^2=u^2 + 2as
5) There are three basic types of motion: translational, rotational and oscillatory.
6) Motion is the process of something moving or changing place, or even just changing position.
