Front

What is the force that keeps objects on top of surfaces instead of letting them sink into the surface?

Back

Normal force.

Front

What is the force exerted by ropes and chains called?

Back

Tension.

Front

What are paired forces?

Back

Forces that are in opposite directions.

Front

If an object experiences 8 N to the left and 4 N to the right, what is the net force? Is this balanced?

Back

Net force is 4 N Left; No, it is not balanced.

Front

What is the definition of normal force?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is tension in physics?

Back

The pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is the difference between static friction and kinetic friction?

Back

Static friction prevents motion between two surfaces in contact, while kinetic friction acts on moving surfaces.

Front

What is the formula for calculating net force?

Back

Net force = Sum of all forces acting on an object.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no change in motion.

Front

What is the role of free body diagrams in physics?

Back

Free body diagrams visually represent all the forces acting on an object, helping to analyze the object's motion.
