A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
An unbalanced force can cause an object to change its speed and or?
The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
What are the 3 classes of levers?
Levers are classified into three types (first-class, second-class, and third-class) depending on the relative position of the fulcrum (pivot point), the point of applied (input) force, and the location of the load (output force). In a first-class lever, the fulcrum is between the input force and the output force, and the load is moved in the opposite direction of the applied force. Placing the fulcrum closer to the load gives an advantage of force (less force needed to move the load a shorter distance), while a fulcrum closer to the point of applied force gives an advantage of distance (the load is moved a greater distance but more applied force is needed). First-class levers include a crowbar, using a hammer's claw end to remove a nail, and a pair of scissors. In a second-class lever, the load is between the fulcrum and the point of applied force, so both forces move in the same direction. Less force is needed to move the load, but the load does not move as far as the direction over which the input force must be applied. Examples include the wheelbarrow, a bottle opener, and a door on its hinges. In a third-class lever, the input force is applied between the fulcrum and the load, and both move in the same direction. The amount of applied force is always greater than the output force of the load, but the load is moved a greater distance than that over which the input force is applied. Examples include a hammer driving a nail and the forearm of a person swinging a baseball bat.

What is a force that can cause an object to change its speed and direction?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
Force can cause an object to change its speed and or direction?
yes, because force is a push or pull, so an example would be that wind (the force) pushed the bike faster toward a building and steered the bike around the building, which causes the bike to change direction. This is an example of velocity too. Velocity is speed in a specific direction.
What do first-class levers always change the direction of?
Ur face
What do first class levers always change the direction of?
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.
What is the IMA of a first class Lever?
The ideal mechanical advantage (IMA) of a first-class lever is 1. This means that the input force and output force are equal in magnitude for a first-class lever. The lever is used to change the direction of the input force rather than to magnify force.
What is the ideal mechanical advantage of a machine that changes only the direction of the input force?
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
What do first class levers do?
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.
Is the lever increase the force to move an object but it does not change the direction of the force?
There are 3 basic types of levers. 1st class, 2nd class and 3rd class. some change the direction of the force, some do not. some increase the force, some do not. A broom is an example of increasing speed, but not force. The direction of the effort (force you put in) and the resistance (force applied to the floor) is the same.
Can a second class pulley change the direction of the effort force?
yes
What are the three classes of levers and an anatomical example of each one?
First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.
What kind of lever is a hinge?
A hinge is a first-class lever because the pivot point (fulcrum) is located between the effort force and the load, allowing it to change the direction of the force applied.
Which can change the direction of a downward input force into an upward output force?
A pulley system or lever can change the direction of a downward input force into an upward output force by redirecting the force through a different path or changing the direction of application. This allows for lifting or moving objects in the upward direction despite the initial force being applied in a downward direction.
What can an unbalanced force cause an object to do?
An unbalanced force can cause an object to accelerate in the direction of the force, change its speed, or change its direction of motion. This is in accordance with Newton's first law of motion.
Does the first class lever make the force greater?
A first-class lever does not necessarily make the force greater. It depends on the placement of the fulcrum and the direction of the applied force relative to the load. A first-class lever can either increase force or increase distance, depending on the specific arrangement of its components.
