When a heart beats, electrical impulses occur in the muscles of the heart. These electrical pulses cause the heart to contract and retract. What force is applied to the blood when the heart muscles contract and pull inward?

• a pulling force, forcing the blood outward through the body

• a pushing force, forcing the blood outward through the body

• a strong frictional force that pulls the blood upward and out of the heart

• a strong gravitational force that pushes the blood upward and out of the heart

Why a ball falls to the ground?

• Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground. 
• Earth's force of gravity is LESS than the ball's, so the ball gets attracted to the ground.
