Question

Define a) speed b) momentum c) 1 dyne​

Answer 1

Answer:

speed is the rate at which an object covers distance speed is a scalor quantity

momentum is the quantity of motion of moving body that measured as a product of its mass and velocity

the force required to accelerate a mass of one gram at a rate of one is 1 dyne

Answer 2

Answer:

Speed :- Speed is a way of measuring how quickly something is moving or being done, or something moving fast.

Speed is directly proportional to distance when time is constant: v ∝ s

Speed is inversely proportional to time when distance is constant: v ∝ 1/t

v = ∆s/∆t

Momentum :- Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p.

Momentum= mass ×velocity

p= m×v

si unit of momentum is kg m/s

1dyne :- One dyne is the force required to cause a mass of one gram to accelerate at a rate of one centimeter per second squared in the absence of other force-producing effects.
