What is seesaw used for?
Seesaw is a simple way for teachers and students to record and share what’s happening in the classroom. Seesaw gives students a place to document their learning, be creative and learn how to use technology. Each student gets their own journal and will add things to it, like photos, videos, drawings, or notes.
Is See Saw free?
The core Seesaw service is free for teachers, families, and students. We also offer Seesaw for Schools with premium features to save time, foster collaboration, and improve family connections – all in Seesaw. …
What is seesaw school?
Seesaw for Schools is a digital app-based platform that allows students, teachers, and parents or guardians to complete and share classroom work. The student portfolio grows over time, allowing them to carry it through their academic career.
How does a seesaw work?
A seesaw is a specific type of lever; it consists of a long beam attached to a pivot called the fulcrum. As soon as you put weight on one end by sitting on one side of the beam it drops to the ground. This is because the force of gravity is acting on the weight of your body, pulling it and the beam down.
What can parents see on seesaw?
Emily Seesaw Product Manager Families only have access to their child’s journal. This means you will see student work tagged with your child’s name and posts the teacher tags with ‘Everyone’. Families will also be able to see any comment made by another user on their child’s journal posts.
Why do they call it a seesaw?
Name origin and variations Seesaw, or its variant see-saw, is a direct Anglicisation of the French ci-ça, meaning literally, this-that, seemingly attributable to the back-and-forth motion for which a seesaw is known. The term may also be attributable to the repetitive motion of a saw.
What is a seesaw sentence?
1) The children are playing at seesaw. 2) There was a sandpit, a seesaw and a swing in the playground. 3) I don’t remember ever being seesaw after I made my mind up. 4) Children all like to seesaw. 5) Marriage, however, is an emotional seesaw.
What class lever is a seesaw?
A lever is a type of simple machine where a rigid arm is arranged around a fixed point or fulcrum. Input, the force you put in, directed into an output force. The classic example of a lever is a seesaw.
How does a seesaw make work easier?
If a force (effort) is applied by pushing down on one end of the lever, the lever turns about the fulcrum to move the resistance (load) up at the other end. When one end of the seesaw is pushed down, the other end goes up. To see how a lever works and why it makes work easier, assemble the lever as shown below.
Is a seesaw a wedge?
An example of a wedge is an ax; An example of a lever is a seesaw; An example of a screw is a screw in the chair that you are sitting in; An example of a wheel and axle is a bicycle with wheels and a chain; An example of a pulley is a flag pole; An example of an inclined plane is a wheel chair ramp.
What is the mechanical advantage of seesaw?
In the above example, the seesaw multiplied Johnny’s force of weight of 15kg by a factor of four. This is the mechanical advantage provided by the seesaw, which represents what is known in physics as a lever of the first kind.
How does a seesaw balance?
In order to balance the seesaw, the two riders, or however many you want to put on the seesaw, have to distribute themselves on opposite sides of the pivot so that their, their torques cancel one another and eventually, if you do it all right, they sum to zero and the seesaw is rotationally inertial.
What is the seesaw principle in math?
In algebraic geometry, the seesaw theorem, or seesaw principle, says roughly that a limit of trivial line bundles over complete varieties is a trivial line bundle. The seesaw theorem is proved using proper base change. It can be used to prove the theorem of the cube.
What is the fulcrum on a seesaw?
The fulcrum/pivot point is the part of the lever that does not move, its in the middle. The work, force applied to the lever, is the person sitting on the other end of the seesaw. The force that is applied by pushing down/pushing up on one end of the seesaw can substitue for the mass on the other end.
What type of motion is seesaw?
Oscillatory motion
What will happen if on a seesaw one child gets up suddenly Why?
When either of the kid sitting on the seesaw suddenly stands up then another kid will quickly fall to the ground below his side of the seesaw. It is because the seesaw works on the principle of the counter-balanced forces of gravity that lets the kid to play in a balanced manner.
How do you construct a seesaw equilibrium?
Seesaws are governed by a simple equation stating that to achieve balance, the force exerted on one end of the seesaw times the distance between the force and the pivot should equal the force exerted on the other side of the seesaw times the distance of that force from the pivot.
What are the two main conditions for equilibrium?
Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.
What is the second condition for equilibrium?
The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a constant angular velocity. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.
What are the three conditions of equilibrium?
A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply :
- The lines of action are coplanar (in the same plane)
- The lines of action are convergent (they cross at the same point)
- The vector sum of these forces is equal to the zero vector.
What keeps the object remain at rest?
Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object.
Does a fast moving object always have higher acceleration than a slower object?
Satellites move at very fast speed around earth but not necessary that their acceleration is large. However a racing car acceleration initially has a very high acceleration but its speed very less as compared to that of satellite.
What is the first law of motion examples?
The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton’s first law. The motion of a kite when the wind changes can also be described by the first law.
What is the formula for Newton’s first law?
Newton’s first law says that if the net force on an object is zero ( Σ F = 0 \Sigma F=0 ΣF=0\Sigma, F, equals, 0), then that object will have zero acceleration. In other words, constant zero velocity—at rest—or constant non-zero velocity—moving with a constant velocity.
What are three examples of Newton’s first law?
Newton’s first law – examples
- A stationary object with no outside force will not move.
- With no outside forces, a moving object will not stop.
- An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever.
- An object at rest stays at rest.
What is the first law of Newton?
Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
