A force is any push or pull. The guy in the picture is exerting a force.
What is mass?
Mass is the amount of matter in an object. It is measured in grams using a triple beam balance.
What is Weight?
Weight is the pull of gravity on an object. Since weight is a measure of force, it can be measured in Newtons.
1 Pound = 4.45 Newtons
What is a Newton?
Newtons are the metric unit for force. It can be measured using a spring scale.
Is there a difference between weight and mass?
Yes. Weight is a measure of force, and mass is a measure of matter. Your mass always stays the same. Your weight can change depending on your location. If you were on the moon, your weight would be different than it is on Earth, but your mass would be the same.
