If several forces act in different directions on a body - in which direction will the body move?
The body will move in the direction of the net force, which is the combination of all the individual forces acting on the body. If the net force is greater in one direction, the body will accelerate in that direction.
Is it possible to have a changing velocity and a constant speed?
Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?
How much work is done on a 60-N box of books that you carry horizontally across a 6-M room?
The work done on the box of books is zero since the force applied by carrying it horizontally does not act in the direction of motion. Work is calculated as force multiplied by distance in the direction of the force, and since the force and distance are perpendicular in this case, the work done is zero.
Whereas impulse involves the time that a force acts work involves what factor?
Work involves both the magnitude of force and the distance over which the force is applied. Work is calculated by multiplying the force exerted on an object by the distance the object moves in the direction of the force.
What will be the direction of friction on a accelerating car by the road?
The direction of friction on an accelerating car by the road is opposite to the direction of the car's motion. As the car accelerates forward, the frictional force between the tires and the road acts in the opposite direction to resist the car's motion and provide the necessary traction for it to move forward without slipping.
What is the definition of a machine?
a device that helps make work easier by changing the size or direction of force
What is a device that makes work easier by changing the size or direction of a force called?
It is called a machine.
3 ways simple machines make work easier?
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
One way a machine can make work easier for you is by?
by changing the direction of the force you applied
What term for a tool that makes work easier by changing the size and direction of a force?
A machine.
What makes your work easier by changing the direction of force?
Changing the direction of force can make work easier by allowing for a more advantageous application of force, such as using a ramp to lift heavy objects or changing the direction of a pulley system to reduce the effort needed to lift weights. It can also help to avoid obstacles or work in confined spaces where a straight force may not be effective.
How do machines make work easier?
A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or direction in which you exert your force.
Which simple machines rely on changes in direction to make work easier?
Simple machines that rely on changes in direction to make work easier include **pulleys** and **levers**. A **pulley** changes the direction of the force, allowing you to lift objects more easily. A **lever** can change the direction of the input force depending on where the fulcrum is placed. visit our website: www. trustlandindia .com/property-type/construction-site/
What is a device that changes the magnitude or the direction of a force?
A simple machine, such as a lever or pulley, can change the magnitude or direction of a force. These devices allow for easier movement of objects by applying force in a different way.
A device that changes the direction or the amount of effort needed to do work?
An inclineded plane
What is a simple michine?
Simple machines are devices that makes work easier- changing size, direction, speed of force
A fixed pulley changes what force?
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
