Forces

Front

What is net force?

Back

The 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 does it mean if forces are balanced?

Back

Balanced forces mean that the total force acting on an object is zero, resulting in no change in motion.

Front

What does it mean if forces are unbalanced?

Back

Unbalanced forces occur when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.

Front

What is friction?

Back

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

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it.

Front

What happens to a moving object when unbalanced forces act on it?

Back

A moving object will change its speed or direction when unbalanced forces act on it.
