How mass of the ball affects the motion of the ball?
Both encounter the same air resistance, but, the heavier ball has a greater downward force which overcomes the upward force of the air. The heavier ball will still reach a t erminal velocity. But, it will accelerate longer than the hollow ball, and its terminal velocity will be greater.
Does force increase when speed increases?
The faster you drive, the greater the impact or striking power of your vehicle. The laws of physics determine that the force of impact increases with the square of the increase in speed. So, if you double the speed of a car, you increase its force of impact four times.
Does more speed equal more force?
They CHANGE the speed. It would be better to say a greater force causes a greater CHANGE in velocity for an object. In that particular case, a greater gravitational force means that the planet must have a circular orbit with a greater speed.
What is the difference between speed and force?
Speed is often used to mean velocity but force relates to acceleration. Speed is often used to mean velocity but force relates to acceleration. Newton’s Second Law states that force equals mass times acceleration. F = maThe higher the force applied to an object the greater will be its acceleration.
Does force affect velocity?
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
Why is velocity not a force?
Velocity does not act on an object. A force pushes or pulls on an object, but velocity is simply something an object has.
Does Lorentz force affect velocity?
Using Lagrange’s equations, the equation for the Lorentz force given above can be obtained again. The potential energy depends on the velocity of the particle, so the force is velocity dependent, so it is not conservative.
Is there force if there is no acceleration?
Acceleration is the change in velocity per unit time. Since the velocity does not change from one moment to the next, then there must be no net acceleration on the object. Returning to Newton’s second law, we can see that if there is no acceleration, then there is no net force.
How can you have no acceleration and still be moving?
Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.
Can a car be moving without accelerating?
Originally Answered: Is it normal for my automatic car to move on putting it in drive without accelerating ? Yes. That’s normal. At a complete stop, the engine in idle, the engine will be pushing on the transmission, and the automatic never fully disengages, so it’ll roll if allowed.
