What causes a ball thrown in the air to fall to the ground?
Answer. This is because the force of earth’s gravitational field is always directed downwards (towards the center of the earth. When the ball is thrown up, it is going against the earth’s gravitational field and so, the earth’s gravitational force pulls it back down, accelerating it downwards.
What force brings the ball down?
gravity
When your notebook is sitting on your table why is it not moving?
The table surface pushes the notebook from below and prevents it from falling. (This force is called the normal force.) Gravity, or a pull from Earth, keeps the notebook from floating in the air. You just studied 34 terms!
Will the ball continue to move if there is no friction?
According to Newton’s first law, if no force is applied to a ball, it will continue moving at the same speed and direction as it did before. Its speed will drop gradually, due to friction (a force applied on the ball in the opposite direction to its motion), but the direction of its motion will remain the same.
What causes a toy car to slow down and stop?
If we push the car we make it move because our push is greater than the other forces acting upon it. We know that one force which causes objects to slow down or stop is friction.
What force will slow a toy car down?
Friction
On which surface would a push car travel the fastest?
Results: The car will move the fastest on the smooth tile, and much slower on the sandpaper and gravel surfaces.
On which surface would a toy car travel the farthest if pushed with the same amount of force?
marble floor
On which surface would a push car travel the slowest Brainly?
Answer. Among the given choices above the correct answer is C. Wooden Floor.
What can you say about the distance Travelled by the toy car or plastic ball?
Answer. 1. The greater the friction, the smaller distance the toy car travels.
What angle gives max height?
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
Which angle produces the greatest height?
60-degrees
