When your mass increases what happens to your weight
If your mass increases, your weight also increases.
A ball is rolled uphill a distance of 3 meters before it slows stops and begins to roll back the ball rolls downhill 6 meters before coming to a rest against a tree what is the magnitude of the balls
The magnitude of the balls displacement is 9 meters.
What is the total displacement of a child who walks 4 m South 2 m North 5 m South and 5 m North
What is the net force acting on a falling object when it reaches terminal velocity
An object falling at terminal velocity is moving at constant
speed (that's what terminal velocity means) and we will assume it
is not changing direction (i.e. it is falling straight down; in
reality it is more likely to be bobbing and weaving on the wind.)
Constant speed and direction is another way of saying constant
velocity. when an object is acted upon by a net force, it's
velocity changes. So, since we know that the velocity is not
changing, there is no force.
For an object moving in a circular path which quantity is always changing
Which factor determines how fast a butterfly is moving
Which gives you a frame of reference for your speed when riding in a train
Which describes a force acting on an object
a ball that moves when kicked
Which is a characteristic of projectile motion
It has variable acceleration
What is a cars acceleration if it increases its speed from 5 m s to 20 m s in 3 s
It accelerates at a speed of 5m/s
What describes the effects of forces on an object
Isaac Newton defines force as mass times acceleration.
Why does an object have a different weight on the moon than it does on Earth
the earth and moon have different values for the acceleration
due to gravity.
What is the frame reference for a plane moving at 500 kmh
