What does horizontally projected mean?
Horizontally projected refers to an object or motion that is launched or moving parallel to the ground in a left-to-right or right-to-left direction, without any vertical component. This means the object is moving along a straight path in a horizontal plane.
What is Air resistance directly proportional?
Air resistance on an object is also referred to as drag. The equation for drag force on an object takes the following form,FD = (1/2) CD A ρ v2where CD is the coefficient of drag for an object of that shape, A is the projected area normal to the direction of air flow, ρ is the air density, and v is the velocity of the air.The force of drag, or air resistance, is therefore proportional to:the projected area of the objectthe density of the airthe square of the velocity
Is the acceleration the same on an object that is drop or when its thrown?
No, the acceleration is not the same for an object that is dropped and an object that is thrown. When an object is dropped, it experiences a constant acceleration due to gravity. When an object is thrown, its acceleration can vary depending on factors such as the initial velocity and direction.
What is an object falling straight down without air resistance said to be exhibiting?
An object falling straight down without air resistance is said to be exhibiting free fall. This means that the only force acting on the object is gravity, causing it to accelerate at a constant rate of 9.8 m/s^2.
What happens to an object if it doesn't have air resistance?
If an object doesn't have air resistance, it will experience no drag force as it moves through the air. This means that the object's motion will be unaffected by the presence of air, and it will travel in a straight line at a constant velocity.
Is it true that neglecting air resistance is a good approximation for the motion of a real object tossed in the air if the object is both light and moving slowly over a relatively short distance?
Not really. Neglecting air resistance just makes it easier to solve equations and grasp concepts. If one were to actually be collecting data from your experiment, they would have to take in air resistance, especially if the object's cross section were high and/or density was low.

When an object is drop disregarding air resistance does a heavier object take less time to fall or have bigger final velocity?
No, neglecting air resistance, all objects fall at the same rate regardless of their mass or shape. Galileo was right about this, as proved on the Apollo 15 mission to the moon. An astronaut on the moon (where there is no air) simultaneously dropped a hammer and feather, and they both fell straight down at the same rate, and hit the ground at the same time.

What is the difference between projected and non projected aids?
A non projected aid used in teaching would be a chalkboard, textbook, or audio with no video capabilities. A projected aid is a visual aid such as a computer with graphics and television.
What is it called when an object falling straight down without air resistance?
It is called Free Fall.
What is the tendency called of a moving object to continue moving in a straight line or a stationary object to remain in orbit?
That tendency is called inertia. It is an object's resistance to changes in its motion and is dependent on its mass.
How does air resistance change speed?
Air resistance acts in the opposite direction of an object's motion to reduce its speed. The force of air resistance or drag is given by the following formula:FD = 1/2 A CD ρ v2whereA is the projected area of the objectCD is the drag coefficientρ is the air densityv2 is the relative velocity of the air
If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
If air resistance is neglected, the motion of an object projected at an angle consists of a uniform downward acceleration due to gravity combined with constant horizontal motion at a constant velocity. The vertical component of the velocity changes uniformly due to gravity, while the horizontal component remains constant throughout the motion.
