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.
When you are running on a road you are act Upon by A frictional force of the road. is there another force acting on you?
Yes, in addition to the frictional force of the road, there is the force of gravity acting on you as you run. Gravity pulls you downward towards the Earth's center, while the frictional force opposes the motion between your feet and the road surface.
What is the frictional force between a tire and a road?
The frictional force between a tire and a road is necessary for the tire to grip the road surface and provide traction for the vehicle to move. This force is influenced by factors such as the texture of the road surface, the materials of the tire and road, and the weight pressing down on the tire. A higher frictional force allows for better control and stability of the vehicle.
What force stops car sinking into road?
The force that stops a car from sinking into the road is the normal force, which is the force exerted by the road surface in the opposite direction to the force of gravity. This force supports the weight of the car and prevents it from sinking into the road.
What is called the force between the tire and the road?
The force between the tire and the road is called frictional force. This force allows the tire to grip the road surface and provide traction for the vehicle to move.
When you are running on a road you are acted upon by frictional force of the road.Is there another force of friction acting on you?
Yes, the force of static friction is also acting between the soles of your shoes and the road surface to help propel you forward while running. This force allows you to push off the ground and move in the direction you want.
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.
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.
What is the average coefficient of friction for a dry road?
The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
What is the force exerted by the wheels pushing backwards on the road?
The force exerted by the wheels pushing backwards on the road is called the frictional force. This force opposes the motion of the vehicle and is necessary for the vehicle to accelerate or decelerate. It depends on factors such as the weight of the vehicle and the coefficient of friction between the tires and the road surface.
What supplies the needed centripetal force in a car turning corner on a valid road?
The friction between the tires and the road surface supplies the centripetal force needed for a car to turn a corner on a valid road. The tires grip the road and create a frictional force that acts towards the center of the turn, allowing the car to change direction.
Which force is responsible for holding a car in an unbanked curve?
The frictional force between the road and the tires is responsible for keeping a car in an unbanked curve. This force provides the necessary centripetal force to keep the car moving in a curved path without sliding off the road.
