List three situations where a force changes the velocity of an object?
When a pitcher throws a baseball, the force from the pitcher's hand accelerates the ball, changing its velocity. When a car applies brakes, the force of friction between the tires and the road slows down the car, changing its velocity. When a rocket launches into space, the thrust from the engines accelerates the rocket, changing its velocity.
What three ways can you change velocity?
Velocity can be changed by changing speed (magnitude of velocity), direction, or both speed and direction simultaneously. This can be achieved by applying a force in the desired direction, changing the mass of the object, or altering external conditions like friction or air resistance.
If displacement is not changing as a function of time then what can we say about velocity?
If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.
When a force is applied to an object what are the three ways it can change the object?
When a force is applied to an object, it can change the object by accelerating it (changing its velocity), deforming it (changing its shape), or moving it (changing its position).
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
What must you have in a problem to adequately describe velocity?

An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.

Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
If displacement is not changing as a function of time then what can we say about velocity?
If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.

When cars are changing direction they are also changing what?
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
Can a body have constant velocity but changing speed?
No, not at all possible. But constant speed with changing velocity is possible.
The process of changing velocity?
Changing velocity involves either increasing or decreasing speed, or changing direction. This can be achieved through acceleration, which is the rate of change of velocity over time. In other words, when an object speeds up, slows down, or changes its direction, its velocity is changing.
Would a merry go round have a changing velocity?
Yes, a merry-go-round would have a changing velocity because it is constantly changing direction as it rotates. The velocity of an object includes both speed and direction, so as the merry-go-round spins, its velocity is constantly changing.
