Why does the acceleration stay constant?
Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.
Why does weight not affect acceleration?
“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.
Does more weight mean more acceleration?
As the acceleration is slower with a heavier car of the same power, you have to accelerate for longer (more time) to cover the same distance so you use more fuel.
Does weight matter acceleration?
Gravity affects weight, it does not affect mass. MASSES ALWAYS REMAIN THE SAME. Newton’s Second Law of Motion: Force = mass x acceleration The acceleration of an object is: a) directly proportional to the net force acting on the object. Move it faster (greater acceleration), because there is less mass, or 2.
What causes a free-falling object to accelerate?
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. The direction of the acceleration due to gravity is downward (towards the center of Earth).
Is Speed affected by weight?
Weight has no effect on speed. However, weight does affect forces, which affects acceleration, which affects velocity with respect to time. More mass needs more force to accelerate the same amount as a smaller mass would. Weight is the force of gravity.
Does weight affect top speed?
The mass of the vehicle will have 0 effect on top speed. Mass only affects acceleration, top speed is determined by the maxmimum power output, and aerodynamic drag. Going up a hill the lighter car will have a higher top speed. Weight and top speed don’t specifically correlate.
Does speed make you lighter?
The faster you move, the slower time beats. Einstein used relativity to show that as you approach the speed of light times beats slower, space contracts and you get heavier. The faster you move, the heavier you get. Energy of motion made you become heavier.
Does Weight Affect horsepower?
No. Horsepower has nothing at all to do with the car’s weight. It is a measure of the maximum power that the car’s engine can produce. All things being equal, a car with fewer pounds for each horsepower will out accelerate one with more pounds per HP.
Is 300 hp enough?
300hp, or horsepower, is not considerably significant. However, It’s plenty of power for most applications! For a sports car, 300hp is a great benchmark, showing that a car will be lots of fun. This means the engine is serious about performance, and likely consumes lots of fuel.
Is it better to have more torque or horsepower?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Does less weight mean more hp?
But in terms of sheer acceleration ability and speed – the higher your power to weight ratio, the better. That means the ideal performance car is lighter in curb weight but jacked to the hilt in horsepower.
What is a good HP to weight ratio?
You should be able to hit about 6/10-8/10 of the cars performance on the street if you push it a bit, but don’t get too dangerous.
How much HP do you need to lose weight?
100 lbs = 10 hp = one tenth (0.10) of a second off of the 1/4 mile time. Therefore, 10 lbs = 1 hp = 0.01 of a second off of the 1/4 mile time. Quote: I remember someone saying 1hp loss per 10lb of weight, so 180lb passenger equal to 18 HP loss net effect.
What is the perfect horsepower to weight ratio?
Simply divide the power output of a vehicle by its weight. For example, if you have a car that weights 2000 pounds and has 250 hp, the PWR will be as follows: 250 / 2000 = 0.125 hp for every pound of car.
