What is when scientists change one object while keeping a matching object the same?
This is known as a controlled experiment. By changing one variable (independent variable) while keeping another constant (control variable), scientists can better understand the effect of the variable being studied. This approach helps to isolate the impact of the changed variable on the outcome being measured.

What two ways can people change the density of an object?
People can change the density of an object by altering its mass or its volume. Increasing the mass while keeping the volume constant will increase density, whereas increasing the volume while keeping the mass constant will decrease density.
How do you change the density of any object?
To change the density of an object, you can either change its mass or volume. Increasing mass while keeping volume constant will increase density, while increasing volume while keeping mass constant will decrease density. Density is calculated as mass divided by volume.
How An Unbalanced force acts on an object differently than a balanced force does?
An unbalanced force causes the object to accelerate in the direction of the force, leading to a change in its motion. In contrast, a balanced force results in no change in the object's motion as the forces cancel each other out, keeping the object in a state of equilibrium.
What causes acceleration to change in an object traveling in a circular path?
As long as the object stays in the same circular path, the acceleration doesn't change. It has to change of the object shifts into a larger or smaller circular path. Just like any other occasion where there's a change of acceleration, it happens when the net force on the object changes.
Why might scientists measure the mass if an object rather than the weight of an object?
Scientists might measure the mass of an object rather than its weight because mass is an intrinsic property of an object that does not change with location, while weight depends on the gravitational pull at a particular location. Mass provides a consistent and accurate measure of the amount of matter in an object, which is useful for making comparisons and calculations in science.
Why might scientists measure the weight of an object rather than the weight of an object?
The mass of an object does not change , but its weight can vary.

Can the direction of velocity of an object change keeping the acceleration constant?
Yes. dv/dt = a=constant.
What happens when scientists add heat energy to an object or take heat energy away from an object?
When scientists add heat energy to an object, the particles in the object gain kinetic energy, causing them to move faster and increasing the object's temperature. When heat energy is taken away from an object, the particles lose kinetic energy, moving slower, and decreasing the object's temperature.

An unbalanced force causes the object to accelerate in the direction of the force, leading to a change in its motion. In contrast, a balanced force results in no change in the object's motion as the forces cancel each other out, keeping the object in a state of equilibrium.
Which forces change the rate and direction of an object in motion?
Any force will change the rate and/or the direction or an object, whether or not it is (initially) in motion.The only exceptions would be if there is something (like a surface supporting it) keeping the object from moving in the direction of the force, or if the object is initially not moving, and the force in not enough to overcome friction.

Why does work done by centripetal force?
The centripetal force does not do work on an object because it acts perpendicular to the direction of motion. It is responsible for changing the direction of the object's velocity, keeping it moving in a curved path, but it does not change the object's kinetic energy.
How do scientists use isotopes to determine the of an object?
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
