newtons is a measurement of force
just substitute that for the sign "N"
so you say that there is 895N per 655kg, so 895kg*m/s*s/655kg
then you cross out the "kg" and do the math, not too bad
The purpose of a keel in a sailboat are to generate lift to counteract the force of the wind. The keel converts the motion of the wind into a forward motion for the sailboat.
When you are stopped at a light, and it turns green, you start to drive forward. That is acceleration.
the mast should not be moved
the wind blows against the sail's and pushes the boat forward
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.
There seems to be a rather wide difference of opinion regarding these aerodynamic/hydrodynamic effects.
moving forward continuesly
The car's acceleration is in forward direction.
That simply means that the direction of the acceleration is relevant. For example, if something is moving in the "forward" direction, it isn't the same if we accelerate it forward, backward, or sideways. The results are different.Also, acceleration is calculated as dv/dt, meaning you divide a velocity difference by a time. Since velocity is itself a vector, acceleration is also a vector.
Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.
