Gravity of the Situation
Vocab Mix-Up
100
An object is being pushed with 12 N to the east and at the same time being pushed with 14 N to the west. The forces are this (balanced or unbalanced).
What is unbalanced?
100
This is the metric unit of force.
What is newtons?
100
According to Newton's 2nd Law of Motion, the rate of acceleration is determined by these two factors.
What are the mass of the object and the amount of force that is applied?
100
The strength of gravitational force is determined by these factors.
What are mass of the objects and the distance between them?
100
This is a force that exists between any two objects that have mass.
What is gravity?
200
A basketball has a mass of 0.625 kg. If the acceleration of gravity on Mars is 3.1 m/s^2, then it weighs this much on Mars. (Round to the nearest tenth of a newton.)
What is 1.9 N?
200
Friction always acts in this direction of a force being applied.
What is the opposite?
200
Newton's 3rd Law of Motion states that for every force there is this.
What is an equal and opposite force?
200
Your pencil exerts a gravitational force on you. This is why you do not feel it.
What is it does not have a lot of mass?
200
This is the resulting force determined by combining all of the forces acting on an object.
What is a net force?
300
An object is being pushed north with 8 N of force, pushed north with another 7 N of force, pushed south with 10 N of force, and pulled north with 6 N of force. This is the net force and direction of movement.
What are 11 N net force and to the north?
300
A type of force that acts upon an object that does not require contact is known as this kind of force.
What is a distance force?
300
This is the reason it takes less force to accelerate a toy car than it does to accelerate a full sized car.
What is the toy car has less mass?
300
This is the reason that the Moon has an effect on Earth's tides and the two closest planets to Earth (Venus and Mars) do not.
What is the Moon is much closer than Mars and Venus?
300
This is a force that opposes the motion of an object.
What is friction?
400
If 65 N of force is applied to accelerate an object at a rate of 13 m/s^2, then the mass of the object is this.
What is 5 kg?
400
This is the type of friction present between a stationary box and the carpet on which it sits.
What is static friction?
400
When a rocket launches, astronauts inside feel like they are being slammed back against their seats. This term is the reason for this.
What is inertia?
400
This is why you would weigh slightly less on the top of Mt. Everest than you would at sea level.
What is the force of gravity is weaker the further you get from the center of Earth?
400
This is an object's resistance to a change in motion.
What is inertia?
500
A toy car consistently increases its velocity from 0 m/s to 4.5 m/s in 5 seconds. If the toy car has a mass of 2 kg, how much force did it take to reach its top velocity?
What is 1.8 N?
500
The type of friction that occurs between a moving truck and the air is known as this.
What is fluid friction?
500
A young boy hits a baseball off a tee and applies an "action force" from the bat to the ball. This is the "reaction force."
What is the ball applying a force to the bat?
500
If a 900 kg rock is dropped at the same time as a feather, the two will land at the same time if this is true.
What is there is no air (occurs in a vacuum)?
500
This is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
What is terminal velocity?
