Calculating Net Force

Front

What is net force?

Back

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 forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the center of the Earth, giving them weight.

Front

In a tug-of-war, if one team pulls with a greater force, what happens?

Back

The team pulling with the greater force will win, and the object (like a ribbon) will move in their direction.

Front

What is an example of a balanced force?

Back

An example of a balanced force is two people pushing against each other with equal force, resulting in no movement.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is a child pushing a swing; if the child pushes harder than the resistance, the swing moves.

Front

How do you calculate net force?

Back

To calculate net force, subtract the smaller force from the larger force when forces are in opposite directions.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
