What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
What happens to your speed if you have a negative acceleration do you speed up or slow down?
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
What happens to the speed when acceleration is in the same direction as the motion?
Speed increase constantly.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
What is a force that causes something to speed up?
A force that causes something to speed up is called acceleration. This force can be produced by pushes, pulls, or gravity acting on an object.
A car is traveling at the same speed until the driver pushes on the accelerator causing a net force to act on the car which in turn causes the car to accelerate.Which of the Newton's Laws explains?
All three of Newton's laws are acting in this situation. Newton's first law states that a body at at rest will remain at rest and a body in constant motion will retain that motion unless a force acts to cause an acceleration. This law explains why the car moves with the same speed until the driver pushes the accelerator. Newton's second law states that the acceleration a body is experiencing is proportional to the force acting on the body to cause the acceleration. This law explains why the amount force the driver puts on the accelerator determines the amount of acceleration the car experiences. The third law states that if body A exerts a force on body B, body B will exert an equal but opposite force on body A. This law explains why the car does not fall through the road surface, why the driver can sit in the car and why the accelerator can be pushed.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
What is a simple example of acceleration?
A simple example of acceleration is a car speeding up from a stationary position at a traffic light. As the driver presses the gas pedal, the car's speed increases, showing acceleration.
The relationship of speed and acceleration?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
How can acceleration be constant if it is an increase in speed?
Exactly the same way that the speed can be constant but the distance keeps increasing.If the acceleration happens to be an increase in speed, then "constant" accelerationmeans that the speed will increase just as much in the 7th minute, for example,as it increased in the 4th minute, for example, etc.Acceleration can be the rate at which speed changes. So if the acceleration is constant,then the speed is changing at a constant rate.(Note: Acceleration doesn't have to be a change of speed. It can also be a changeof direction, at constant speed.)
What happens to an objects speed if it travels with zero acceleration?
If an object travels with zero acceleration, its speed remains constant. This means that the object maintains the same speed throughout its motion and does not change its velocity.
