Combining Forces and Friction

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration and direction of movement.

Front

How do you determine the direction of net force?

Back

The direction of net force is determined by the direction of the greater force acting on the object. If forces are balanced, the net force is zero.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.

Front

What are the types of friction?

Back

The main types of friction are static friction (preventing motion), kinetic friction (during motion), and rolling friction (when an object rolls over a surface).

Front

What is balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to accelerate in the direction of the greater force.

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object. It can also affect how easily an object starts moving.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Force applied (F_applied) - Frictional force (F_friction).

What happens when two forces act in the same direction?

Back

When two forces act in the same direction, you add their magnitudes to find the net force.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, you subtract the smaller force from the larger force to find the net force.
