1. Newton's Second Law (F=ma). The tennis ball has less mass, so for the same applied force, it experiences a greater acceleration, making it easier to roll.
2. Newton's First Law (Inertia). The car continues moving in a straight line at constant speed on the low-friction ice surface until an external force (like friction or a collision) acts on it.
3. Newton's Second Law (F=ma). A harder push means a greater force is applied to the box, resulting in a greater acceleration and thus a higher final speed.
4. Newton's Third Law (Action-Reaction). When Ashely pushes the water backward (action), the water exerts an equal and opposite force forward on the kayak (reaction), propelling it.
5. Newton's Second Law (F=ma). The truck has much more mass than the car; to achieve the same acceleration, it requires a proportionally larger force, which necessitates a larger engine.
6. Newton's First Law (Inertia). The ball continues moving after being kicked due to its inertia, but friction from the ground (an external force) eventually stops it.
7. Newton's Third Law (Action-Reaction). When the ball hits the ground, it exerts a downward force on the ground (action), and the ground exerts an equal upward force on the ball (reaction), causing it to bounce.
8. Newton's Third Law (Action-Reaction). The rocket expels exhaust gases downward (action), and the gases exert an equal and opposite upward force on the rocket (reaction), propelling it into the air.
9. Newton's Second Law (F=ma). Swinging the racquet harder applies a greater force to the ball, resulting in greater acceleration and a higher final velocity.
10. Newton's First Law (Inertia). Kyle's body continued moving forward at its original speed when the car suddenly stopped, demonstrating inertia; the seat belt provided the external force needed to stop him.
