Back

Normal force.

Front

True or False: The greater the mass of a brick placed on a countertop, the greater the normal force exerted on the brick.

Back

True.

Front

What is the sensation of having a different weight due to force exerted on you by the floor, like in an elevator?

Back

Front

What is a sketch that shows all the forces acting on an object called?

Front

What is the force exerted by a string, rope, or wire that is pulled tight?

Back

Tension.

Front

Define 'normal force'.

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What happens to the normal force when the angle of an inclined plane increases?

Back

The normal force decreases as the angle of the incline increases.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What does a free body diagram represent?

Back

It represents all the forces acting on an object, showing their direction and magnitude.
