Forces practice test questions

Front

What is a free body diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does the normal force represent in physics?

Back

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

Front

What is the relationship between mass and inertia?

Back

Inertia is the resistance of an object to change its state of motion, and it is directly proportional to the mass of the object.

Front

What happens to gravitational force as mass decreases?

Back

The gravitational force decreases as mass decreases.

Front

What is static friction?

Back

The force that resists the initiation of sliding motion between two surfaces in contact.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

What is the role of tension in a system?

Back

Tension is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is the coefficient of friction?

Back

A numerical value that represents the frictional force between two surfaces in contact, affecting how easily they slide past each other.

Front

What is the effect of increasing the angle of a ramp on parallel weight?

Back

As the angle of a ramp increases, the parallel weight acting down the ramp increases.
