Forces, Net Force, Force Diagrams

Front

What is a force?

Back

A force is a push or pull acting on an object.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the net force.

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 is a force diagram?

Back

A force diagram is a visual representation of all the forces acting on an object, showing their direction and magnitude.

Front

If two forces of 30N are acting in opposite directions, what is the net force?

Back

The net force is 0N.

Front

If a girl pushes with 20N to the right and a boy pushes with 15N to the right, what is the net force?

Back

The net force is 35N to the right.

Front

What does it mean if an object is at rest?

Back

An object is at rest when the net force acting on it is zero.

Front

What does it mean if an object is accelerating?

Back

An object is accelerating when the net force acting on it is not zero, causing a change in its velocity.
