Can an object in free fall can be considered to be moving horizontally?
Yes, an object in free fall can be considered to be moving horizontally if it was given an initial sideways velocity. However, as the object falls, the vertical component of its motion will accelerate due to gravity, causing the object to ultimately move in a curved path known as a projectile motion.
What are not examples of free fall?
An object moving horizontally, an object resting on a surface, and an object in space with no gravitational force acting on it are not examples of free fall. Free fall specifically refers to an object falling solely under the influence of gravity.
What forces do not cause a change in momentum?
Internal forces, such as the force of gravity on an object moving horizontally, do not cause a change in momentum. Additionally, forces that do not act in the direction of an object's motion, like perpendicular forces, do not affect the momentum of the object.
How does moving an object at an angle affect work?
Moving an object at an angle can increase the work done on the object compared to moving it in a straight line. This is because work is equal to the force applied in the direction of motion multiplied by the distance the object moves. When moving at an angle, the force required to displace the object is split between moving it horizontally and vertically, increasing the overall work done.
What are the forces acting on a moving object?
The forces acting on a moving object include: gravity, friction, air resistance, and any applied forces such as pushing or pulling. These forces can affect the speed, direction, and motion of the object.
How would no air affect the motion of objects moving horizontally?
It depends on the surface on which the object is moving, and also any other forces - such as gravity.
How does gravity affect object that are moving horizontally?
The force of gravity is the same, whether the object doesn't move at all, whether it moves horizontally, vertically, diagonally, or whatever. The force is about 9.8 newton/kilogram.Therefore, if no other forces act on the object, it will accelerate downward at a rate of 9.8 meters/second squared - again, no matter how the object is moving at any given time. Under gravity (and assuming no other forces are significant - such as air resistance), an object that initially moves horizontally will have the tendency to move in a parabola.

What are the differences between projectile motion and free fall?
Projectile motion involves an object moving both horizontally and vertically, while free fall is when an object falls only vertically due to gravity. In projectile motion, the object has an initial horizontal velocity, while in free fall, the object is only affected by gravity.
Describe two forces that can affect an objects velocity?
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
What are the similarities in motion of a free-falling object and an object that is projected horizontally?
Both a free-falling object and an object projected horizontally experience only the force of gravity acting on them. They both follow a parabolic path due to gravity, with the horizontal motion of the projected object not affecting the vertical motion caused by gravity.
Why does a force of gravity has no effect on horizontal component of velocity?
The force of gravity only acts vertically, causing objects to accelerate downward. It does not affect the horizontal motion of an object. This means that an object will continue moving horizontally at a constant velocity, unaffected by gravity, as long as no other forces are acting on it in the horizontal direction.
What is An object moving in a curved path affected only by gravity is called a?
An object moving in a curved path affected only by gravity is called a projectile.
