Exploring Force Video Notes

What is the scientific definition of a force?

• The movement of an object in a specific direction

• Any push or pull on an object in a specific direction

• A measure of the gravitational pull on an object

• The resistance an object offers to change in its state of motion

What is net force?

• The strongest force acting on an object

• The sum of all forces acting on an object

• The force that is not opposed by any other force

• The weakest force acting on an object

What happens when forces are balanced?

• The object moves in the direction of the stronger force

• The object's motion does not change

• The object accelerates

• The object automatically reverses direction

What does it mean when the net force is zero?

• The object is in a vacuum

• Forces acting are equal and opposite

• Forces are unbalanced

• No forces are acting on the object

What is an example of unbalanced forces resulting in motion?

• Opening a door

• Two teams pulling equally in tug of war

• A book resting on a table

• One team pulling harder in tug of war

Which scenario describes an unbalanced force?

• A tug of war with equal teams

• Pulling a wagon with more force than friction

• A car parked on a flat road

• Pushing against a closed door with no movement

What happens to an object when unbalanced forces act on it?

• It remains stationary

• It moves in the direction of the stronger force

• It disintegrates

• It moves in the direction of the weaker force

How do you calculate the net force when forces are unbalanced?

• Add all the forces together

• Subtract the smaller force from the larger force

• Divide the larger force by the smaller force

• Multiply the forces
