Why does a ball fall straight down?

Its y-axis velocity, the speed at which it moves downwards, is determined purely by gravity, just as in the case of the dropped ball, as none of the throwing force is directed downwards. Both the balls have the same velocity along the y-axis and therefore should reach the ground at the same time.

What causes objects to fall to the ground?

The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. All its mass makes a combined gravitational pull on all the mass in your body.

Why don t things fall straight down?

Gravity is the force of attraction that makes things fall straight down.” But say it to a physicist, and the answer you’ll get is, “That’s right.” The exception is physicists: They know that nobody knows what gravity is, because they know that they don’t know what gravity is.

Why dont things fall straight down?

It is because the acceleration due to gravity is constant for all objects regardless of the mass, neglecting air resistance. This is because it only depends on the mass of the earth but the force the object exerts when it hits the ground varies with its mass.

Why do objects fall down in a straight line when moving?

Objects fall down in a straight line relative to the moving car (constant velocity), not relative to the ground speeding by outside. The object in the car (like the occupants) shares the velocity of the car. The object moves in a parabola compared to the ground, which can be considered to be at rest.

Why do objects fall in front of cars when accelerating?

That’s because you are dropping the object inside the vehicle. You and the object are moving with the vehicle with the same velocity. Try dropping the object during hard acceleration or braking and it will either fall behind or in front.

What happens when you hold an object while driving a car?

If the vehicle is moving at a constant speed and you’re holding an object, your arm and that object are going at the same speed as the vehicle. It’s because of this that, if you drop the object, it will land more or less where you dropped it.

What happens when you drop an object at 100 km/h?

While the car is travelling at 100km/h, the object you drop is also travelling at 100km/h as the car has accelerated you, and the object you are going to drop to the same speed. Ie. you, the object, and the cars interior are all at rest in the reference frame of the car.
