The angular momentum of a planet remains constant in its motion around the sun. This is due to the conservation of angular momentum, which dictates that the product of the planet's mass, velocity, and distance from the sun remains the same as the planet orbits.
The tendency of an object to remain at rest or in motion with a constant velocity is known as inertia.
Horizontal motion is constant when there are no external forces acting on an object in that direction. According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. This is why horizontal motion can remain constant when there is no acceleration or deceleration.
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
The feather is likely in a balanced state of forces where air resistance is equal to the force propelling it forward, such as a gentle breeze. As long as the forces remain balanced, the feather will continue at a constant velocity. This is a demonstration of Newton's first law of motion.
this my sound rather daft but this is a bit of a trick question, the speed is the same so straight away you would think the acceleration is constant right....???? Wrong the displacement of the object is changing (displacement is the distance being travelled with a direction, a vector quantity.) as the displacement is changing so is the velocity, as velocity is displacement/time. as the velocity is changing so is the acceleration because acceleration is then change in velocity divided by time.

No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.

Newton's first law of motion tells me that I will remain in constant uniform motion unless I am acted on by an external force.

Newton's first law of motion is often stated as: "An object at rest will stay at rest unless acted upon by an outside force. An object in motion will remain in motion at a constant speed and direction unless acted upon by an outside force." Motion, If an object is not ifluenced by any force other then its motion, its velocity will naturally remain constant. i.e, it will continue to move along in a perfectly straight line at a constant speed.
No. The definition of acceleration is change in velocity.

If no force acts on an object, it will remain at rest if it was initially at rest, or continue moving at a constant velocity if it was already in motion. This is known as Newton's first law of motion, which states that an object will remain in its state of motion unless acted upon by an external force.
Density is a fixed quantity for a particular compound because it is calculated using the formula mass divided by volume, which gives a specific value for a given substance. This value will remain constant as long as the mass and volume of the substance remain unchanged.
