What else can I help you with?
The momentum before a collision of three objects is always greater than tha momentum after the collision?
Not necessarily. The total momentum of a system of objects is conserved unless external forces are present. In a collision involving three objects, the total momentum before the collision could be equal to, greater than, or less than the total momentum after the collision, depending on the specific circumstances of the collision.
What experiment of Galileo's involved cannonballs?
Galileo's experiment to show that mass had little effect on the speed of falling objects involved two cannonballs of different sizes being dropped from a certain height. This showed that, in a vacuum at least, falling objects fall at the same speed no matter their mass.
Are objects heavier on Venus' or Mars?
They are heavier on Venus due to it's larger mass.
Can an objects acceleration increase if you drop it from a higher altitude?
Yes, an object's acceleration remains constant regardless of the height from which it is dropped. However, the object will achieve a higher velocity when it lands after being dropped from a higher altitude due to its longer time in free fall.
Is the following sentence true or false squeezing and stretching matter involves elastic forces?
True. Squeezing and stretching matter typically involves the activation of elastic forces within the material. These forces allow objects to return to their original shape after being compressed or extended.
Which is the force that pulls a ball to the ground after being dropped?
The force that pulls a ball to the ground after being dropped is gravity. Gravity is the natural force of attraction between two objects with mass, in this case, the ball and the Earth.
What two factors do gravity depend on?
The forces that arise on account of gravity depend on the masses of the objects being attracted toward each other, and on the distance between their centers.
What are examples of Objects that are distorted by external forces?
ANY object on which an external force acts will be distorted. The distortion MAY be too small to be obvious. An example would be any object resting on some surface - the force being the force of gravity.
Why don't objects dropped at the same height land in the same place?
Because it didnt fell like being in the same place. lol
Do pencils fly?
No, pencils do not have the ability to fly on their own. They require external forces such as being thrown or dropped for movement.
How is contact forces and mechanical forces different from gravitational and magnetic forces?
Contact and mechanical forces involve direct physical contact between objects, such as pushing or pulling. Gravitational and magnetic forces act at a distance without the need for physical contact, with gravity being a force between masses and magnetism a force between magnetic objects.
What do you notice about the density in sinking objects?
Sinking objects have a density greater than the fluid they are placed in. This causes them to sink due to the force of gravity being greater than the buoyant force acting on them. Objects that sink typically have a higher mass per unit volume compared to the fluid they are in.
The momentum before a collision of three objects is always greater than tha momentum after the collision?
Not necessarily. The total momentum of a system of objects is conserved unless external forces are present. In a collision involving three objects, the total momentum before the collision could be equal to, greater than, or less than the total momentum after the collision, depending on the specific circumstances of the collision.
When the mass is greater what is the gravity?
Other things being equal, more mass will cause more gravity.
You are both pulling the same object in opposite directions at first the object doesn't move then it does what are you when the objects move?
You are applying a force to the object, but in opposite directions. The object doesn't move at first because the forces are balanced. Once one force overcomes the other, the object begins to move in the direction of the greater force.
What happens when two objects of different masses are dropped in a vacuum?
In a vacuum, where there is no air resistance, two objects of different masses will fall at the same rate and hit the ground at the same time. This is due to the acceleration of gravity being the same for all objects in a vacuum, regardless of their mass.
When two objects are placed together horizontally is there friction between them?
If they are touching yes and the harder they are being pushed together the greater the friction.
