What else can I help you with?
Why is it really hard to push a car to start moving it but it is easy to push it to keep it moving?
newtons first law. An object in motion stays in motion. Its inertia keeps it going
What force is needed to give a 2000 kg car an acceleration of 1.5 m cubed?
F = M a = (1,300) x (1.5) = 1,950 newtons
What do Forces come in?
Yes, but not nesicarially equally. "In every interaction, forces always occur in pairs. For example, in walking across the floor you push against the floor, and floor pushes against you. Likewise, the tires of a car push against the road, and the road in turn pushes back in the tires. In swimming you push the water backward, and the water pushes you forward. There is a pair of forces acting in each instance. The forces in these examples depend on friction; a person or a car on ice, by contrast, may not be able to exert the action force against the ice to produce the needed reaction force." -Conceptual Physics by Paul G. Hewitt
Why are magnets and cranes needed to move cars?
If the car is broken, you have to move it with something that can carry the entire weight of the car....
Does it take more force to push a car or skateboard?
first of all the car is heavier than a bicycle. and a bicycle only has 2 thin wheels while a car has 4 broad wheels. thus there is more contact. hence there is more friction.
Is it easier to push a car or a bus?
It's easier to push a car because the force needed to push it is less.
Two cars accelerate at a rate of 3mps the mass of each car in kilograms is 1250 and 200 how many more newtons of force are needed to accelerate the car with the larger mass?
F=ma, Force=(mass)(Accleration), (3)(1250)-(3)(200)= 3,150 Newtons

How many newtons are acting on a still car?
Thrust can affect a car in two basic ways.The cars drive train system creates thrust to push it down the road and the wheels can create thrust to change its direction, all basically the same thing based on the friction created by the tires and force applied by the car through them.External thrust from wind and other factors like a crash. These forces try to push the car around by blowing or pushing the car.
What force is needed to give a 2000 kg car an acceleration of 1.5 m cubed?
F = M a = (1,300) x (1.5) = 1,950 newtons
How many newtons of force does it take to move a car?
The force required to move a car depends on various factors such as the weight of the car, road conditions, and incline. On average, it can take anywhere from a few hundred to a couple thousand newtons of force to move a car.
How many newtons does a car going 30mph have?
The force of an object in motion, such as a car traveling at 30 mph, can be calculated using the formula Force = mass x acceleration. Without the mass of the car, we cannot determine the force in newtons.
How does Newtons 2 law explain why it is easier push a bicycle than to push a car with the same acceleration?
Essentially you're looking at F = ma acceleration, a = the same for both vehicles. The mass, m of a bike is much less than that of a car therefore; The required force to push a bike is much less than that required for a car. Therefore it's easier to push a bike.
Why a greater force is needed to push a car up a ramp?
When pushing a car up a ramp, gravity is pulling the car back down the incline. To counteract this gravitational force and move the car upwards, a greater force is needed to overcome the resistance caused by gravity. This is why a greater force is required to push a car up a ramp compared to on a flat surface.
How many grams does a car sunshade weigh?
Weight is measured in Newtons, not grams - which is a measure of mass.
How much force is needed to accelerate a 1-kilogram toy car at a rate of 2 meters per second?
Force = Mass * Acceleration = 1 * 2 = 2 Newtons
What is the magnitude of the net force needed to bring a 2175 kg car to rest from 24.2 meters per second in 7.4 seconds?
approximately 7000 newtons
