8.6A -- Forces

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its speed or direction. It occurs when the total forces acting on an object are not equal.

Front

What happens when a cyclist turns sharply while moving?

Back

The forces acting on the cyclist are unbalanced because the direction of motion changes.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

In a tug-of-war, if one group pulls harder than the other, what type of force is acting?

Back

An unbalanced force is acting, causing the rope to move towards the stronger pulling group.

Front

What is the net force?

Back

The net force is the overall force acting on an object after all the individual forces are combined.

Front

If a force causes an object to move at a constant speed, what type of force is it?

Back

It is a balanced force.

Front

What is the effect of an unbalanced force on an object at rest?

Back

An unbalanced force will cause the object to start moving.

Front

What is the relationship between force and motion?

Back

Force is needed to change the motion of an object, including starting, stopping, or changing direction.

Front

If two forces of 400 N and 250 N are applied in opposite directions, what is the net force?

Back

The net force is 150 N in the direction of the larger force.

Front

What does it mean if an object is at rest and the forces acting on it are balanced?

Back

It means that the object will remain at rest because the forces cancel each other out.
