Net Forces Review

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.

Front

What is a balanced force?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero. The object remains at rest or continues to move at a constant speed.

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 in the direction of the greater force.

Front

What can cause an object to accelerate?

Back

An imbalance between two or more forces can cause an object to accelerate.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object is either at rest or moving at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

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 the object's mass.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the movement.
