Does the speed change if air resistance is a factor?
The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. The change in velocity terminates as a result of the balance of forces. The velocity at which this happens is called the terminal velocity.
Does landing of both coins on the floor depend on the speed?
ANS : Target response: Both objects fall at the same speed. Mass does not affect the speed of falling objects, assuming there is only gravity acting on it.
What happens when two coins collide?
Engage. The faster a penny is moving, the more energy it possesses. When objects collide, energy can be transferred from one object to another, changing their motion.
What happened if you flicked the card from underneath instead of from the side?
Watch it as long as you like but, on it’s own, the penny will not move from that spot. When you flick the card out from under the penny, you allow gravity (an outside force) to act on it and drop it into the glass. The bottom of the glass stops the penny from falling.
What happens to the egg as you pull the cardboard abruptly to the side?
Answer: For a brief nanosecond or two, the egg didn’t move because it was already stationary (not moving). But then, as usual, the force of gravity took over and pulled the egg straight down toward the center of the Earth.
Why does a coin fall into the cup?
Explanation: The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn’t fast enough to overcome that force. If you flick it quickly, the coin stays in one place and then drops into the cup.
What force caused the penny to fall into the cup?
gravity
What happens when we drop a coin in a glass of water?
Light bends when it passes from one medium (water) into another medium of a different density (air). This bending of light, called refraction, causes the apparent position of the coin to change to a shallower position​1​ (see diagram). The light bends when it passes from water to air on top of the water.
Can an object be moving in a straight line if there are no forces acting upon it?
f there is no net force acting on a body, it will continue in its state of rest or will continue moving along in a straight line with uniform velocity. The net, or total, force acting on the object is zero Newtons. It will move in a straight line. It will not change direction.
Can an object experience a non zero acceleration if there is no change in velocity?
Acceleration depends on the change in an object’s velocity. An object moving at a constant speed can experience a nonzero acceleration if the direction of the object’s motion changes.
