A race car driver can keep the same engine but increase the acceleration of the car by making the holes bigger in the carburetor template. This part is also called a restrictor plate because if it has smaller holes, the car cannot go as fast as with larger holes.
Yes, force is the gravitational acceleration multiplied by the mass of that object. Should the gravitational acceleration increase (as on a different planet) or should the object's mass increase, the gravitational force on the object will as well.
Usually time but it could depend on the specific graph.
force, mass, acceleration, and u could argue impulse
1 Newton is defined to be the force which will accelerate 1Kg at an acceleration of 1 metre per sec per sec. In general F=MA Newtons for Mass M Kg and acceleration A metres per sec per sec. So you could say the units of force are MLS-2 but people prefer to say "Newtons" instead.
Acceleration is a vector, meaning each acceleration has both magnitude and direction. The resultant of vectors is basically the net acceleration on the object expressed as a single vector. For example, if there are two vectors each with a magnitude of 2 meters/(seconds squared) acting on an object and these vectors were placed on the x and y axes then you could represent this system of 2 vectors 90 degrees apart each with a magnitude of two meters/(seconds squared) as one vector of 45 degrees with a magnitude of 2 times the square root of 2 meters/(seconds squared).
The driver could use different sized tires or reduce the amount of friction.
suppose that 5he acceleration of acar increase with time could we use v=v0+at
The acceleration would be increased if the person pushing started to use a greater force. This would increase the force but keep the mass constant.
definant possibility. with a broken motor mount, the engine will lift up during acceleration thus causing vibration.
bums
what do you mean with ease? BTW an F1 driver and a fighter jet driver can sustain 5G.
If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
It's lean. Could be something plugged in the carb.
The year, make, model and engine info would help but in general it could be a vacuum leak or time for a tune up.
Could be timing belt/chain is worn
perhaps water pump, or clutch bearings. Get thee to an auto mechanic.
Timing is probably off.
