What is force?
A force is any push or pull on an object that can change the current motion of an object.
What is a newton?
A newton is a unit of measure for force.
What is the sum of forces?
The sum of forces describes the addition and/or subtraction of forces acting along the same line. Another name for the sum of forces is the net force.
What is a net force?
The net force is the sum of all forces acting on an object.
What are balanced forces?
Forces are balanced on an object when the sum of forces acting on the object is zero. This implies that the forces acting on an object have equal strengths and act in opposite directions. The motion of an object remains unchanged when the forces acting on the object are balanced.
What are unbalanced forces?
Forces are unbalanced on an object when the sum of forces acting on the object is not zero. The motion of an object changes when the forces acting on the object are unbalanced.
What does “at rest” mean?
At rest means that an object is not moving or changing its position in space.
Forces can be balanced or unbalanced. But exactly what does that mean? How can you tell if the forces acting on an object are balanced? Get started now to play a game of tug of war to investigate balanced and unbalanced forces.
