When driving on slick roads why is it advisable to apply the break slowly?
If you apply the breaks quickly on a slick road, the wheels' rotational movement will come to a complete stop, but the car itself will keep moving forward, causing the car to slip. It happens because the force of friction, Ff, is small. The traction of the wheels on the ground (which requires that the wheels continue to roll at the speed that the ground moves past them, which is what normally happens) is what allows the driver to maintain control of the car. If the wheels suddenly were not gripping the ground, which would happen if their rotational motion stopped, the driver would have not control over the car. Slowly applying the breaks is advised because the force of friction is not exceded by the force of the breaks. In otherwords, friction (traction) still causes the wheels to roll, mainting the driver's control over the car. If the force of the breaks exceeds that of friction, then the wheels will come to a stop before the car does.
What happens to a soccer ball if you apply a force?
If you apply a force to a soccer ball, it will accelerate in the direction of the force. The speed and direction of the ball will depend on the magnitude and direction of the force applied.
What happens when someone pushes a chair across the floor?
When someone pushes a chair across the floor, the force applied in the pushing direction causes the chair to move. Friction between the chair legs and the floor resists the motion, which can create a sound as the chair moves. If the force is strong enough, the chair will accelerate and continue moving until the force is removed or balanced by other forces.
What is the action force when you sit down on a chair?
The action force when you sit down on a chair is the force exerted by you on the chair. This force is equal in magnitude and opposite in direction to the reaction force exerted by the chair on you, which supports your weight and keeps you from falling through the chair.
What happens when someone pushes a chair across the room using newtons second law of motion?
When someone pushes a chair across the room using Newton's second law of motion, the chair accelerates in the direction of the force applied. This acceleration is directly proportional to the force applied and inversely proportional to the mass of the chair. As long as the force is greater than any opposing forces like friction, the chair will continue to accelerate in the direction of the push.
What are the examples of balance force?
If the forces on an object are balanced, it won't move. This would apply to a captive balloon, held to the ground by a rope. The upward force of the balloon's buoyancy is balanced by a downward force in the rope, and these must be equal. The same argument for you sitting still in your chair, your weight is balanced by an upward force in the chair.
What happens when you apply force in an object in space?
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
What action and reaction forces are present when you are sitting in a chair?
When you sit in a chair, the action force is the downward force you exert on the chair due to your weight. The reaction force is the upward force exerted by the chair on you, supporting your weight and keeping you from falling to the ground.
If you push a chair across the floor at a constant velocity how does the force of friction compare with the force?
If the chair is moving at a constant velocity, the force of friction is equal and opposite to the force you are exerting on the chair. This is to maintain the equilibrium of forces acting on the chair.
Why doesn't the force you exert when sitting on a chair cause the chair to move?
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
How strong is the upward force exerted by your chair as you sit in it?
The upward force exerted by a chair when you sit on it depends on your weight and the design of the chair. The force is equal to the force of gravity acting on you, to keep you balanced and prevent you from falling.
Which Newtons law of motion can explain what happens when someone pushes a chair across the floor?
It will have no equilibruim and when you are pushing it you are using a force
