## Step 1The first question is about the force that causes objects to fall towards the Earth. The options provided are electrical force, free fall, friction, and gravitational force. ## Step 2The correct answer is gravitational force. This is because the Earth's gravity pulls objects towards its center, causing them to fall. The other options, electrical force, free fall, and friction, do not cause objects to fall towards the Earth.## Step 3The second question is about the concept of deceleration. Deceleration is defined as a decrease in velocity. ## Step 4The statement is true. An object whose velocity is changing is indeed said to be decelerating. This is because the velocity of an object can either increase (acceleration) or decrease (deceleration).
