What is a balanced force?

Back

A balanced force is a situation where the net force acting on an object is zero, resulting in the object being at rest or moving at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the larger force.

In which direction will an object move when acted upon by unbalanced forces?

Back

An object will move in the direction of the larger unbalanced force.

What happens to the forces when skateboarding down a ramp?

Back

The forces are unbalanced when skateboarding down a ramp, causing the skateboarder to accelerate downwards.

What is the definition of net force?

Back

Net force is the vector sum of all the forces acting on an object, determining the object's acceleration.

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, sum all the forces acting in one direction and subtract the sum of forces acting in the opposite direction.

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change an object's motion; the object remains at rest or continues to move at a constant speed.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table, where the gravitational force downward is balanced by the normal force upward.

What is the relationship between mass and force in Newton's second law?

Back

According to Newton's second law, force equals mass times acceleration (F = ma), indicating that greater mass requires more force to achieve the same acceleration.

What is inertia?

Back

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