- Normal force is the force acting on an object in a direction perpendicular to the surface of contact.
- It is the force that keeps objects from sinking into the surface and must be large enough to negate any acceleration into the surface.
- When an object is traveling at a constant velocity, it is in equilibrium, which means that it experiences no net force. The only force, other than the normal force, acting on the block is the gravitational force. A free-body diagram will show that the gravitational force will be equal in magnitude and in the opposite direction to the normal force.
- Gravitational force for objects close to the surface of the earth is Fg = mg.
- The normal force will be large enough in magnitude to yield zero net force.
Fnet = mg - FN
0 = 10010 - FN
FN = 1000 N

Given:
- Mass of the block of wood, m = 100 kg
- The block is traveling with a constant velocity on ice
We are asked to find the normal force acting on the block.
Explanation:
The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
When an object is at rest or moving with a constant velocity, the net force acting on it is zero. In this case, since the block is traveling with a constant velocity, the net force acting on it is zero.
The forces acting on the block are:
1. Weight (mg): The force due to gravity acting on the block, which is equal to the mass of the block multiplied by the acceleration due to gravity, g. Since the block is on ice, it is not in contact with the ground, so the normal force is not equal to the weight of the block.
2. Normal force (N): The force exerted by the surface (ice) to support the weight of the block. Since the block is traveling with a constant velocity, the normal force must be equal in magnitude and opposite in direction to the weight of the block, in order to cancel out the weight and keep the net force zero.
Therefore, the normal force acting on the block is equal to the weight of the block, which is given by:
N = mg
Substituting the given values:
N = (100 kg)(9.8 m/s^2) = 980 N
So, the correct answer is option D) 1000 N.
- Mass of the block of wood, m = 100 kg
- The block is traveling with a constant velocity on ice
We are asked to find the normal force acting on the block.
Explanation:
The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
When an object is at rest or moving with a constant velocity, the net force acting on it is zero. In this case, since the block is traveling with a constant velocity, the net force acting on it is zero.
The forces acting on the block are:
1. Weight (mg): The force due to gravity acting on the block, which is equal to the mass of the block multiplied by the acceleration due to gravity, g. Since the block is on ice, it is not in contact with the ground, so the normal force is not equal to the weight of the block.

Since the block is traveling with a constant velocity, the normal force must be equal in magnitude and opposite in direction to the weight of the block, in order to cancel out the weight and keep the net force zero.
Therefore, the normal force acting on the block is equal to the weight of the block, which is given by:
N = mg
Substituting the given values:
N = (100 kg)(9.8 m/s^2) = 980 N
So, the correct answer is option D) 1000 N.
