What is a change in velocity or direction?
Any change in speed or direction is a change in velocity. That's an acceleration,and it directly implies the presence of force, since it can't happen without force.
Can uniform angular velocity has acceleration?
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
What is the acceleration of a car moving in a straight line at a constant rate of 29 meters per second for 4 seconds?
"Constant rate" implies there is no acceleration - acceleration is zero.
Can particle with constant velocity be accelerating?
No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.
What can forces cause a change in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.
What can forces cause changes in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.
How are motion and acceleration different?
In Simple motion, there is no force being applied. The moving object moves in a straight line with constant velocity. In acceleration, there is a force applied. The object's velocity is changing. The first derivative of acceleration is velocity. The first derivative of velocity is distance. (Derivative is a calculus thing.)
Is increasing acceleration the same as positive acceleration?
Yes, increasing acceleration means that the rate of change of velocity is increasing, which implies positive acceleration. Positive acceleration corresponds to speeding up, while negative acceleration (deceleration) corresponds to slowing down.
What is the difference between the multiplier and the accelerator?
the multiplier principle implies that investment increases output whereas the acceleration principle implies that increases in output will themselves induce increases in investment.
Does the presence of hydrogen bonding in a substance imply the presence of dipole-dipole interactions as well?
Yes, the presence of hydrogen bonding in a substance implies the presence of dipole-dipole interactions as well.
What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
Any change in velocity is what?
acceleration
