The goalie's mass is high and the net force is low. Therefore the acceleration is lower. However the goalie is big so his hit on the other player is still a big hit.


To move a heavy object, or an object with a great mass, it will require a great net force. This means that the total force acting on the object must be large.Mass is said to be inversely proportional to acceleraction. This means that when mass goes up, acceleration goes down, and when mass goes down acceleration goes up. Net force is directly proportional to acceleration. When net force increases, so does acceleration. And when net force decreases, acceleration does the same. This is because it must overcome the friction force which slows it or even keeps it in place. If an object is not accelerating it could still be moving. This is because it could be moving at a constant velocity. The other option for an object not accelerating is that it is at rest.

Newton's second law of motion states, "The acceleration of an object is produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This can be simply said that if something is heavier its going to be harder to push it and accelerate it. If it is light than it will be easier to move and accelerate. This also means that mass is inversely proportional to acceleration. In the picture the the Southern Miss. player hits the Cal player. The net force was enough to move the player despite his mass.
