Speed
What is speed?
the distance traveled by an object divided by the time taken to travel that distance
Is it true that acceleration is the speed of something in a given direction??
No, that is false
What is velocity?
the speed of an object in a particular direction
There's two people on opposite sides of a rope they are both pulling on it with the same force this is called a
Balanced Force
What is Newton's 1st Law?
An object at rest stays at rest and an object in motion stays in motion unless another force acts upon it.
A rocket travels 3000 meters in 5 seconds. How fast is it travelling?
3000/5 = 600 meters per second.
A motorcycle travelling 90 mph accelerates to pass a truck. Five seconds later the car is going 120 mph. Calculate the acceleration.
6 mph/second
What's the difference between speed and velocity?
Velocity must have a direction
One person is pushing a box towards the right with a stronger force and the other person is pushing to the left with less force this is called a
unbalanced force
What is Newton's 3rd Law?
For every action there is an equal and opposite reaction
How fast is a runner travelling if she covers 100m in 12s?
8.33m/s
An ambulance is currently traveling at 15m/s and is accelerating with a constant acceleration of 5 m/s2. The ambulance is attempting to pass a car which is moving at a constant velocity of 30m/s. How far must the ambulance travel until it matches the car’s velocity?
67.5 m
A person riding a bike travels 214 meters in 58 seconds. Calculate the person's velocity.
3.7 meters/second
One person is pushing a box towards the right with (50N) and the other person is pushing to the left (60N) so, therefore the net force is
Is it true of false that rowing a boat considered an example of Newton's 3rd Law?
A police car accelerates quickly to 60 meters per second in order to pursue a minivan that is recklessly speeding along the highway at 45 meters per second. How long will it take the police car to catch up if the minivan is 600 meters ahead of the police car at the beginning of the chase?
40 seconds
A Boeing 747 aircraft has a landing speed of 72 m/s, and upon landing it is able to come to a stop in 2,000 m. Assuming constant deceleration, how long would it take for a Boeing 747 to come to a full stop?
56 seconds
A speedboat maintains a constant velocity of 12.00 meters per second. Calculate the time it will take for the boat to travel 400.00 meters.
33.33 s
8N to the left and 14N to the right. What is the net force? Is it balanced?
The net force is 6N to the right and no it isn't balanced
Is a soccer ball getting hit into a wall and coming to a complete stop a example of the 1st Newton Law?
Yes, it is
A train maintains a constant velocity of 16.0 meters per second. Calculate the distance the train has traveled after 26.0 seconds.
416m
A Ferrari Enzo is able to reach a speed of 134 miles per hour (60 meter/sec) from 0mph in 11 seconds. Assuming constant acceleration, how far would the Enzo travel in this amount of time?
330 meters
A car maintains a constant velocity of 18.0 meters per second. Calculate the distance the car has traveled after 1.50 minutes.
1,620 m
Two people are pushing an object to the right with the same force (20N) and two other people are on the opposite side (the left). One person from that side is pushing with the force of 30N and the other person in that same side is pushing with 40N. What is the net force?
Who created the 3 Newton Laws?
Issac Newton
