What happens to the balls velocity while the ball is up vertically in the air?
The ball's velocity decreases as it moves upward due to the opposing force of gravity. At the peak of its trajectory, the velocity momentarily becomes zero before the ball starts descending and its velocity increases back in the downward direction.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.
Two balls a and b are moving towards each other with speeds 5ms and 2ms respectively. what will be the velocity of a just after a perfectly inelastic head-on collision?
In a perfectly inelastic collision, the two objects stick together after the collision. The velocity of the objects after collision will be a weighted average of their initial velocities based on their masses. The velocity of ball a after collision can be calculated using the formula: (m1 * v1 + m2 * v2) / (m1 + m2), where v1 and v2 are the initial velocities of balls a and b, and m1 and m2 are the masses of balls a and b respectively.
Is anything bad happening in Ecuador?
balls
What happens when two balls collide?
When two balls collide, energy is transferred into sound and deformation, but momentum remains the same. The mass times velocity of the balls is constant.
What is the ball's acceleration?
Well that depends. What is the balls starting and ending velocity? And for how long?
Which ball if dropped has more velocity a bouncy ball or a tennis ball?
This is an old experiment. Neither. Both balls have the same velocity as gravity draws on them equally.
Can something have both a constant velocity and constant acceleration?
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.
What If you have four balls all traveling at 5 meters per second which one has the most kinetic energy?
All four balls would have the same kinetic energy since kinetic energy is determined by both the mass and velocity of the object. If all four balls have the same mass and velocity, their kinetic energy would be equal.
What is happening to an object when it has a negative accerleration?
It's deccelerating-it's slowing down-it's losing velocity.
What happens to the balls velocity while the ball is up vertically in the air?
The ball's velocity decreases as it moves upward due to the opposing force of gravity. At the peak of its trajectory, the velocity momentarily becomes zero before the ball starts descending and its velocity increases back in the downward direction.
A balls is thrown upwards with a velocity of 10 ms How high does it go?
The ball goes up 5.1 meters.
When a car's velocity is positive and it's acceleration is negative what is happening to the car motion?
The car is slowing down
Two balls of different masses are thrown vertically up from the same point and at the same time The two balls will experience the same change in?
Two balls of different masses are thrown vertically up from the same point and at the same time. The two balls will experience the same change in :there velocity.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
