Acceleration
Why seatbelts are mandatory equipment in vehicles?
So if you crash you won't go flying out the window from the acceleration.
to change its (____), at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
What is velocity?
When you jump off a small rowing boat into water, you will push yourself forward towards the water.
What is force?
(100 points) Speed: What is speed?
To tell how fast something/someone is going around objects.
Why do bird flap their wings to fly in the air?
Cause they are using force to flap.
(100 points ) Friction: What is friction.
Friction is the force resisting the relative motion of material elements sliding against each other.
There is a 5 mile drag strip. First car went 58 mph. The second car went 60. Which car went faster.
The First car won because if they had a slower speed but they had faster Acceleration than the other car which made them go faster and reach the line before the second car.
58 divided by 5 = 11.6 60 divided by 5 = 12
A train travels west for 460 km. The trip takes 10 hrs. What is the trains velocity.
46 km/hr west
Final Question: When was Newton's laws of motion found?
1687
(200 points) Speed: The destination is 400 miles. The trip is going take 15 hours. What is the speed if the car?
The speed of the car is 26 mph.
if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Is that the first law, second law, or third law?
What is the first law.
What is the second law.
Either a change in speed or direction.
What is Velocity
if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Is this the First second third?
What is the third law?
