Force Diagrams

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of motion.

Front

What does a leftward force applied to a crate at constant speed indicate in a force diagram?

Back

It indicates that the leftward force is balanced by an equal rightward force, resulting in no net force and constant speed.

Front

What is Newton's 1st Law?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the normal force?

Back

The normal force is 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 role of friction in motion?

Back

Friction is a force that opposes the relative motion of two surfaces in contact, affecting the acceleration and speed of moving objects.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the force that pulls objects toward the Earth.

Front

What is tension force?

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion (net force = 0), while unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Sum of all forces acting on an object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, directly related to its mass.
