Work = Force times displacement
The work done on an object is equal to the Force (push/pull) on the object in Newtons times the distance (in meters) that the object moves.
If you push or pull on an object and it does NOT move (zero displacement), then no work is done on the object.

False. Work is directly proportional to the distance applied. The amount of work done increases as the distance over which the force is applied increases.
True. Work is done when an object moves in the direction of the force applied to it. Work is calculated as the force applied multiplied by the distance the object moves in the direction of the force.
False. Work is done whenever a force is applied to an object and there is a displacement in the direction of the applied force, whether the object moves in that direction or not. In cases where the object does not move, work is still done as long as there is a force applied over a distance.
True. Work is measured in joules, where 1 joule is equal to the work done when a force of 1 newton is applied over a distance of 1 meter in the direction of the force.
The law of applied for states that bodies change in mass and proportional to the amount of force applied to it is false.
False. A lever to multiply the force exerted has its fulcrum closer to the object than to the force is applied. This will increase the force but decrease the distance the object moves compared to the force end.
No, this statement is not accurate. The work done is determined by the force applied and the distance over which that force is applied, not just the distance alone. The amount of work done depends on both factors and is independent of the distance moved alone.
Torque is the combination of perpendicular distance and weight; it is not a true force
False. Work is defined as the product of the force applied on an object and the distance over which it travels. In this case, if the distance traveled is 0 meters, then no work is being done on the object regardless of the force applied (25 N in this scenario).
The statement is not only false, but absurd as well.
true
True. Some machines, such as levers or pulleys, don't multiply the force applied to them but instead change the direction or distribution of the force, making it easier to exert the force in a specific way.
