What is the mass of an object that needs a force of 6600 N to increase its speed from rest to 170 ms2 in 2.3 seconds?
To find the mass of the object, you can use Newton's second law, which states that force (F) equals mass (m) multiplied by acceleration (a): F = ma. Rearranging the formula to solve for mass gives m = F/a. Plug in the force of 6600 N and the acceleration of 170 m/s^2, then calculate the mass.

Why when density increase buoyancy force increase?
When density increases, the buoyancy force increases because the difference in density between the object and the fluid it is immersed in also increases. This difference in density creates a greater upward force, which is the buoyant force. This is because as the object's density increases relative to the fluid, more fluid needs to be displaced to counteract the weight of the object, resulting in a greater buoyant force.
What is the term for the force of gravity on an object that needs to be lifted?
The force of gravity on an object that needs to be lifted is called the object's weight. This weight is the measure of the force of gravity pulling the object downward towards the Earth.
Why does an object in orbit needs a centripetal force act?
An object in orbit needs a centripetal force to keep it moving in a circular path. Gravity provides this centripetal force, pulling the object towards the center of the orbit. Without this force, the object would continue in a straight line tangent to the orbit.
What is needed to make an object accelerate?
To make an object accelerate, a force needs to be applied to the object. This force can come from various sources such as gravity, friction, or propulsion. The magnitude and direction of the force will determine the rate at which the object accelerates.
What is required to set an object into motion?
To set an object into motion, a force needs to be applied to overcome its inertia. This force can be in the form of a push, pull, or any other mechanism that imparts energy to the object. Once the force is greater than the object's inertia, it will start moving.

How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
What 2 things need to occur for work to happen?
For work to happen, there needs to be a force applied to an object and the object must move in the direction of the force. Work is calculated as the product of force and distance moved in the direction of the force.
What is needed to make something move?
To make something move, a force needs to be applied to the object. This force can come from various sources such as pushing, pulling, gravity, or a motor. The object will then accelerate in the direction of the force applied.
Does the acceleration of an object rolled down an incline increase if it gets smaller?
No, the acceleration of an object rolling down an incline does not increase if the object gets smaller. The acceleration is determined by factors such as the incline angle, gravitational force, and the object's moment of inertia, but not its size.
What force needs to touch something i to effect it?
The force of contact is required to affect something physically. This force occurs when one object comes into direct contact with another, resulting in a push or pull that changes the object's motion or shape.
What is needed for an object to move?
For an object to move, it needs a force to act upon it. This force can be exerted through actions like pushing, pulling, or gravity. Additionally, the object must be free to move, with no constraints holding it in place.
What two things do potential and kinetic energy need to gain more energy?
Well, basically, the higher an object is above the ground, the more potential energy it has. For kinetic energy, the amount of energy depends on the amount of force.
