What does constant velocity mean?

It means moving at a constant speed ... not speeding up or slowing down ... and in a straight line.


If Sara's father presses on the brakes quickly slowing the car down what slows Sara down?

When Sara's father quickly presses on the brakes, the car decelerates due to the friction between the brake pads and the brake discs. As the car slows down, Sara's body tends to continue moving forward due to inertia, which is the tendency of an object in motion to remain in motion. The seatbelt and the car's interior ultimately help slow her down by applying force to her body, bringing her to a stop along with the vehicle.


What is a rate of change of velocity with time?

The rate of change of velocity with respect to time is called acceleration. It measures how quickly the velocity of an object is changing. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).


When does an object have no acceleration?

When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.


What does mean the velocity remains constant?

When an object's velocity remains constant, it means the speed and direction of the object's motion do not change. This implies that the object is moving at a consistent rate without speeding up, slowing down, or changing course.


An object is neither speeding up nor slowing down travels at a?

An object that is neither speeding up nor slowing down travels at a constant velocity. This means its speed remains the same over time, covering equal distances in equal intervals.


With which constant velocity the disk rotates at a constant speed?

The disk rotates at a constant speed when the angular velocity remains constant. This means the disk rotates at a constant angular velocity, maintaining a consistent rate of rotation without speeding up or slowing down.


What is the angular acceleration of the minute hand of a clock?

The hands of a clock move at a constant speed, not slowing or speeding up. Therefore, the acceleration is a constant 0 rad/s2


When the slope of v t graph is negative and constant what is the nature of acceleration?

acceleration is the slope of the v t graph... so the acceleration is constant and negative. In other words, the object is slowing down at a constant rate.


Why car still accelerates after slowing down?

Acceleration is a change in velocity. Assuming a constant direction, if you're speeding up that is positive acceleration. If you are slowing down, that's negative acceleration. Either way you are accelerating.


What does it mean when we say that an object moves with constant speed?

When we say an object moves with constant speed, it means that the object is moving at the same rate without speeding up or slowing down.


What are the 3 most important times to check traffic behind you are?

Backing, changing lanes, or slowing down quickly.
