After a shove, a cart is initially moving in the direction of the weaker of two unbalanced forces acting on it. What would eventually happen to the motion of the cart?
What is the cart would slow down gradually before reversing?
When a hand in pushing on a cart, the hand is exerting what onto the cart?
What is force?
If a fan cart were started from rest and allowed to run forever what would happen?
What is it would continue to speed up?
Is friction a force?
What is yes?
How would a fan cart's motion be different if a stronger fan were used to speed it up or slow it down?
What is its speed would increase or decrease at a faster rate?
If two fans are pushing in the same direction with its strength being 30N and 40N while a 65N frictional force acts in the opposite direction, what is the net force?
What is 5N?
When a hand is exerting a force onto a cart, what happens to the cart?
What is the cart speeds up?
What would happen if the fan blade jammed as it was pushing a cart along a track?
What is the cart would stop speeding up immediately?
In which direction does friction act?
What is opposite to the direction of an object's motion?
If two carts of the same mass were raced and ended in a tie, what could be inferred about the strength of the force exerted onto the carts?
What is they were the same strength?
If a cart with two equally strong fans pushing in opposite directions was given a quick shove to start it moving, what would happen after?
What is the cart would continue to move at a reasonably constant speed?
When a hand is not exerting a force onto a cart, what happens to the cart?
What is it moves at a constant speed?
What would a speed-time graph look like if a cart was pushed along a track by a continuous, constant force?
What is a constant increase?
If you were to drop two spheres of similar sizes, but different masses, from the same height at the same time, which would hit the ground first?
What is they would reach the ground at the same time?
If two carts raced ended in a tie and both carts were pushed with the same amount of force, what could be inferred about the mass of the two carts?
What is they had the same mass?
How does the net force for an object with balanced forces compare to the net force for an object with no forces?
What is they are the same?
Why does a cart lose speed after a hand loses contact with the cart?
What is there is no longer any force pushing the cart?
What is definite evidence that supports the idea that a force is pushing an object forward?
What is motion with increasing speed only?
Why would a 6lb cart and a 2lb cart reach the ground at the same time if dropped from the same height?
What is the 6lb cart is pulled down 3x stronger than the 2lb cart?
When the same strength backward force acts on two carts with different masses that are initially moving at the same speed, which cart will slow to a stop and reverse direction first?
What is the cart with less mass?
When one object pushes continuously on another, how do the forces they exert on each other compare?
What is the relative force strengths will always be equal?
During a contact push-pull interaction between two objects, what is transferred from one object to the other?
What is a similarity between a single force acting on an object either toward the direction of motion or against the direction of motion?
What is they cause a change in speed?
What would need to be done to make a race between a 6lb cart and a 2lb cart end in a tie?
What is increase the strength acting on the 6lb cart by 3?
Three carts participated in a race. Cart A weighs 3lbs. Cart B 2.1lbs. Cart C weighs 6.7lbs. Which cart will win the race?
What is Cart B?
