true
Anything that moves in a path that's not straight can do that.
Motion implies momentum, which implies velocity. Linear implies a straight line. Accelerating implies changing velocity. And uniform implies constancy. So, when an object moves in a straight line and accelerates at a constant rate, you have uniformly accelerating linear motion.
If it is a horizontal straight line, it means the object is moving at constant velocity. If it is a sloped line, it means the object is accelerating.
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
Zero acceleration if it is traveling in a straight line. An object that is accelerating must either be changing its rate of speed or its direction.
That's correct.
No, if a car is traveling in a straight line at a constant speed, it is not accelerating. Acceleration refers to a change in speed or direction, which is not occurring in this scenario.
A constant force in the direction of the line
No, a jogger moving at a constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the jogger's speed remains constant, there is no acceleration.
Anything that moves in a path that's not straight can do that.
No, a body moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed of the body remains constant, there is no acceleration. For example, a car moving at a steady 60 mph on a straight road is not accelerating.
Straight line at a constant speed = no acceleration
It will have constant motion vertically while accelerating horizontally.
It will have constant motion vertically while accelerating horizontally.
Motion implies momentum, which implies velocity. Linear implies a straight line. Accelerating implies changing velocity. And uniform implies constancy. So, when an object moves in a straight line and accelerates at a constant rate, you have uniformly accelerating linear motion.
If the cart is moving at a constant speed in a straight line, it is in uniform motion. If the cart is changing its speed or direction, it is accelerating.
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
