Question

consider this situation: a baseball player dives head - first into second base and slows down while sliding on the infield dirt. of the forces listed, identify which act upon the player.
tap to select the forces that are present.
normal gravity applied
friction tension air resistance

Explanation:

• Normal force: The ground exerts a normal force perpendicular to its surface on the player.
• Gravity: The Earth's gravitational pull acts downward on the player.
• Friction: The infield dirt exerts a frictional force opposite to the direction of the player's motion, causing the player to slow down.
• Air resistance: There is a small force due to air resistance acting opposite to the direction of the player's motion (though usually small compared to friction in this context but still present).
• Applied force: There is no external applied force (like a push from another object) mentioned in the situation.
• Tension: There is no rope or string etc. involved, so no tension force.

Answer:

Normal, Gravity, Friction, Air Resistance
