Forces

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 motion.

Front

What happens when two teams pull with the same amount of force?

Back

If two teams pull with the same amount of force, they will not move at all, as the forces are balanced.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an example of balanced forces?

Back

A train moving at a constant speed in the same direction is an example of balanced forces.

Front

What is the net force when forces are equal and opposite?

Back

The net force is 0 N when forces are equal and opposite, meaning there is no acceleration.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate.

Front

What is the formula for calculating net force?

Back

Net Force (F_net) = Force applied (F1) - Force opposing (F2).

Front

What is inertia?

Back

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

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is required to change its motion (Newton's second law: F = ma).

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.
