What does the normal force exerted by a table do to a block resting on it?
What does the normal force exerted by a table do to a block resting on it?
- It pushes the block sideways.
- It creates friction with the block.
- It opposes the weight of the block. (correct)
- It pulls the block downward.
In the equation N - W = 0, what does N represent?
In the equation N - W = 0, what does N represent?
- Normal force acting on the block (correct)
- Frictional force against the block
- Net force on the block
- Weight of the table
What relationship does the normal force have with the weight of the block when at rest?
What relationship does the normal force have with the weight of the block when at rest?
- The normal force is irrelevant when the block is in motion.
- The normal force is always less than the weight.
- The normal force is equal to the weight of the block. (correct)
- The normal force is always greater than the weight.
If the weight of a block is given by W = mg, what would be the equation for the normal force on that block?
If the weight of a block is given by W = mg, what would be the equation for the normal force on that block?
What condition is met when a block is in equilibrium on a table?
What condition is met when a block is in equilibrium on a table?

Normal Force Definition
Normal Force Definition
The upward force a surface exerts on an object resting on it, counteracting the object's weight.
Normal Force Equation
Normal Force Equation
The normal force (N) equals the object's weight (W).
Weight Equation
Weight Equation
Weight (W) equals mass (m) times acceleration due to gravity (g).
