What force other than gravity is pushing on a rock when it sinks?
The "buoyant" force is acting on it, in the vertically upward direction. That force is equal to the weight of the water that would be in the volume of the rock if the rock weren't there.
Acceleration of a rock at the top of its trajectory when thrown straight upward?
Any object moving under the influence of gravity only and no other outside forces has a constant acceleration of 9.8 meters (32.2 feet) per second2, directed down.The speed changes. The acceleration doesn't, regardless of the angle, speed, trajectory, color, temperature, cost, size, mass, or weight of the falling object.
Neglecting air resistance what is the net force that acts on a 1-kg rock that is thrown strait upward when it is half way to the top of its path?
10 newtons
When you use a crowbar to lift a heavy rock which force is bigger the weight of the rock or the force applied to the end of crowbar?
the force, otherwise the rock would not move.
When a rock thrown straight upwards gets to the exact top of its path is?
zero
Acceleration of a rock thrown straight upward at the moment it reaches the tippy-top of its trajectory?
9.8 m/s (2) Squared

What causes the soil and rock to fall?
When the ground thaws, the force of gravity causes the soil and rock particles to fall back down. But they fall vertically, toward the center of Earth. The result is movement downhill.

What is the acceleration of a 3kg rock that is thrown with a force of 18N?
Newton's Law F=ma A=F/M A=18/3 A=6m/s2
Did Justin Bieber get a rock thrown at him?
Justin Bieber has had a rock thrown at him by a fan trying to get his attention! But luckily it just missed him.
What forms when lava flows vertically a layer of rock?
dike

What effect of the sweeping in curling?
The friction from sweeping heats the ice slightly and reduces the friction between the rock and the ice. This does two things; it makes the rock travel farther, and it also makes the rock travel straighter. When a rock is released, depending on the type of shot being thrown, the players will judge whether sweeping will help or hurt the trajectory of the rock, and decide whether the rock should be swept or not. Usually, the sweepers will pay attention to whether the rock might need sweeping to travel farther, while the skip pays attention to whether the rock might need sweeping to travel straighter, and they communicate this with each other while the rock travels down the ice.
What happen to kinetic energy of the rock as it gets higher and higher?
Unless the speed of the rock changes, the kinetic energy does not change. If you are talking about a rock that is being thrown, of course the kinetic energy decreases as kinetic energy is converted into potential by the conservative gravitational force.
