Homework Statement
What can be said about a car traveling at constant velocity on a street, keeping in mind Newton's first law?
Homework Equations

My first reaction to this question is "But a car is not a particle." Assuming the car is a particle, then it...
I did an experiment on a force table with pulleys and weights. We were suppose to, through trial and error, find weights and add them on strings that were placed at different angles, so that the ring in the middle would become centered. Attached is the data table. I am suppose to calculate the...
I have just done an experiment with a glider on an air track and applied a force to it. Its velocity increased very slightly and was wondering are there any reasons, other than friction, why the velocity could change during motion? Thanks
I thought this but i don't know if its right "There...

Newton's first law states that a body in motion tends to stay in motion and that's why when you're driving a car and then suddenly stop you get pushed at the same speed you were traveling.
the Earth orbits the sun at 64,000 miles and the Earth's rotation is 1000 miles per a hour.

Consider this situation: A police officer arrives at the scene of an accident and finds a load of straw bales partly on the back of a pickup truck and partly on the hood of a Jaguar sedan. Both vehicles are facing in the same direction. The pickup is in front of the...
What is the point of Newton's First Law? The first law says that "The state of motion of an object will not change unless acted upon by an outside force". In layman's terms, this means that the object's velocity won't change unless there is a net force (at least that is how our physics teacher...
Okay, so its stated that a body in motion stays uniformly in motion unless influenced by an external force. But what happens if that force is internal? For example, a rock moving in space that explodes from the inside. This causes the rock to fragment and move in different directions. This has...
Im wondering what situations involving objects in motion , you could take advantage of Newton's first law of motion?
I have one situtaion but I am not sure of another one that could be considered taking advantage of Newton's law...
I read the following question in a Yr11 High School Physics Test.
A trolley is traveling along at unifrom velocity when a weight is dropped onto it which stays there.
The velocity of the trolley will...
A) Decrease
B) Increase
C) Stay the same
?
The answer says "decrease"...
Please ,
Explain me this situation
A spider is attached to two threads of equal length that make a 120o angle with each other. The spider is motionless and its mass is m=30mg.
What is the tension in each thread?
According to the Newton first Law, the sum of the force must be 0...

What really is INERTIA?
Is it a force.?
A vector or a scalar?
What can be known only by the defination?
Does it really have anything to do with physics?
*Just noticed that I posted in the wrong thread. Sorry about that is there any way I can move it to the right thread?*

I don't understand how to even begin with this problem.
Here it is: An arrow, starting from rest, leaves the bow with a speed of 26.0 m/s. If the average force exerted on the arrow by the bow were doubled, all else remaining the same, with what speed would the arrow leave the bow?

I've recently brought a physics book, and in it are some questions, which go throughout different chapters. at the moment i am on Newton's first law of motion.
I looked at one of the questions on it and it asks
" Explain how a car can skid on a icy road?"
I remember reading in the...
