Forces and Newton's Laws

Front

What is net force?

Back

The net force is the total force acting on an object after 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 0 N, and the object remains at rest or continues to move at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What factors affect friction?

Back

The amount of friction depends on the types of surfaces in contact and the force pressing them together.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of objects moving through the air.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, always acting in an attractive manner.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Total forces acting in one direction - Total forces acting in the opposite direction.

Front

What is an example of balanced forces?

Back

Two people pulling on opposite ends of a rope with equal force, resulting in no movement.

Front

What is an example of unbalanced forces?

Back

A person pushing a shopping cart forward while another person pulls it backward with less force, causing it to move forward.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.
