What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

If two people pull a box with forces of 6N and 3N to the right, what is the net force?

Back

The net force is 9N to the right.

Front

What is the direction of an object if the net force is to the right?

Back

The object will move to the right.

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

Give an example of a balanced force.

Back

Pushing against a wall is an example of a balanced force.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Give an example of an unbalanced force.

Back

A football entering a 3-point goal at increasing speed is an example of an unbalanced force.

Front

What happens to an object when the net force is zero?

Back

The object remains at rest or continues to move at a constant speed.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Front

What is an example of a new substance being formed by a chemical reaction?

Back

Milk souring is an example of a new substance being formed.
