A jack for a car requires a force of 120 lbs to lift a 3000 lb car what is the ratio of the car's weight to the force required to lift the car write the ratio in simplest form?
25:1
What is the centripetal force when a car is turning a bend?
For any body to move along a curved path instead along a straight path, its direction of the speed often changes. Hence velocity changes. To make the velocity changing we need acceleration. Hence a force is required. Such a force is named as centripetal force. Also known to be centre seeking force. This is said to be the essential force for a movement along a curved path. Such centripetal is provided by the frictional force in between the moving tyre and the floor. If suppose oil or granules of sand is there on the road, then slippery would occur and hence skidding happens.
What factors are true about centripetal force?
Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
How do you make a toy car move by force?
you push it
What is the importance of law of inertia?
The law of inertia is more popularly known as Newton's first law of motion. And that simply says that: An object in motion tends to stay in motion or a body at rest tends to stay at rest unless otherwise acted upon by a net force. This is important in day to day life because it says that when things are moving, like you walking or your car rolling, it will take some sort of braking force to stop that motion. Conversely, if you or your car is at rest, the law says you need to exert some force to get walking or put the pedal to the floor to get the car moving. In sum you are exerting forces to stop or start motion of yourself or of objects all the time. And when you do that you are acknowledging the law of inertia.
How big is the frictional force when a car stops on a flat road?
Very big because it has no grip on the surface for the frictional force to stop and it takes time to stop the car.
Describe the size and direction of the frictional forces when a car stops on a flat road?
When a car stops on a flat road, the frictional force acting on the car is static friction and its direction is opposite to the direction of motion. The magnitude of the static frictional force is equal in magnitude and opposite in direction to the force applied by the car's brakes to bring it to a stop.
What are the example of frictional force?
bike racing car racing
The brakes on a car exert a frictional force of 6000 N in getting the car to stop If the work done by the brakes is 120 000 J in coming to a stop how many meters did the car travel after the driver?

A 1500 kg car accelerates at 4.4 ms2 on a level stretch of road If there is a wind resistance force of 67 N what must be the frictional force between the tires and the road?
The total force acting on the car is the sum of the force of the car's acceleration and the force of wind resistance. To find the frictional force, subtract the force of wind resistance from the total force acting on the car. The frictional force between the tires and the road is equal in magnitude but opposite in direction to the net force acting on the car.
What is the 3 net force of a car rolling down a ramp?
The net force acting on a car rolling down a ramp is the result of the gravitational force pulling it downwards and any frictional forces resisting its motion. Generally, the net force will be equal to the component of the gravitational force parallel to the ramp minus the frictional force.
When the road is wet it takes times longer to stop?
Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.
Which forces are working when car moving in forward direction?
When a car is moving in the forward direction, the main forces at play are the engine force propelling the car forward, the frictional force between the tires and the road providing traction, and air resistance acting against the car's motion. These forces work together to keep the car moving in the desired direction.
What then can you seay about the acceleration of the moving car?
It is directly proportional to the force applied by the engine adjusted for the frictional force, aerodynamic drag, and inversely proportional to the mass of the car.
Why does your car run short of engine oil very fast after filling it?
Because of Frictional Force
How do you decrease velocity of a moving car?
You increase the frictional force by applying the brakes.
How the centripetal force is provided to a car to take a turn?
In a car taking a turn, the centripetal force required to keep it moving in a curved path is provided by the friction between the tires and the road. As the car turns, the frictional force between the tires and the road acts as the centripetal force, pulling the car towards the center of the curve and preventing it from sliding outwards. The car's tires generate this force through their contact with the road surface.
