The increase in speed of objects is typically caused by the application of a force in the direction of motion, as described by Newton's second law of motion (F=ma). This force can be generated by various means, such as pushing, pulling, or gravity. Additionally, reducing friction or air resistance can also contribute to increasing an object's speed.

Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
Falling objects accelerate due to gravity at a rate of approximately 9.8 m/s^2 near the surface of the Earth. This acceleration is constant and causes objects to increase in speed as they fall.
Objects accelerate as they fall to the ground due to the force of gravity acting on them. As the object falls, the force of gravity causes it to increase in speed, resulting in acceleration. This acceleration is a result of the unbalanced force acting on the object.
When interference occurs, the change in a marble's speed is caused by the interaction between the interfering objects. The force exerted by the interfering object on the marble can either increase or decrease its speed, depending on the direction and magnitude of the force applied.
Yes, the acceleration due to gravity causes objects to fall faster the longer they are in free fall. The acceleration due to gravity is approximately 9.8 m/s^2 near the surface of the Earth. It causes objects to increase in speed by 9.8 meters per second every second they fall.
