Calculating Net Force

Front

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

How do you calculate net force when forces are in the same direction?

Back

To calculate net force when forces are in the same direction, add the magnitudes of the forces together.

Front

How do you calculate net force when forces are in opposite directions?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to an object if the net force acting on it is zero?

Back

If the net force acting on an object is zero, the object will remain at rest or continue to move at a constant velocity.

Front

What is the formula for calculating net force?

Back

The formula for calculating net force is: Net Force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces.

Front

What is an example of balanced forces?

Back

An example of balanced forces is a book resting on a table. The force of gravity pulling the book down is balanced by the normal force from the table pushing it up.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is a soccer ball being kicked. The force of the kick is greater than the friction and air resistance, causing the ball to accelerate.

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.

Front

What is the relationship between mass and force?

Back

The relationship between mass and force is described by Newton's second law: Force = Mass x Acceleration (F = ma).
