Which of Newton’s Laws is f=ma?
1st Law
3rd Law
2nd Law
What causes a rocket to launch from a space shuttle into the emptiness of space?
The rocket’s engine pushes fuel and gases against the ground, concentrating force.
The rocket’s expelling fuel puts a force on the rocket and the gas puts an equal force on the rocket.
The rocket uses a different source of energy to launch into space.
None of the above answers are correct .
Riqui Puig steps on a peddle boat floating on a lake and the boat moves in the opposite direction as he steps on it. Why does the boat move in the opposite direction?
Riqui Puig applies a force to the boat, as he steps on it, which causes the boat to move in the opposite direction, where the boat applies an equal and opposite force on Riqui Puig.
The boat moves in the opposite direction because Riqui Puig has a big mass, which the boat cannot contain, therefore, pushing away from Riqui Puig.
The water current is very intense, causing the boat to move away.
Riqui Puig applies too much force on the boat, causing it to move in the opposite direction. If Riqui Puig applied a smaller force, then the boat would move towards his direction.
Phil Foden negligently puts an open cup of soda in his car When he’s driving he slams on the brakes to avoid a car wreck. According to Newton’s 3rd Law, which direction does the soda escape?
To the right
To the left
Backward
Forward

The normal force is straight towards the center of the earth.
Bernardo Silva releases a balloon, which law causes the balloon to fly through the air?
3rd Law, equal and opposite reaction.
1st Law, equal and opposite reaction.
2nd Law, law of acceleration.
1st Law, law of inertia.
A tree branch falls off of a 50 ft tree, at a distinct time the weight and the drag force acting on the branch become equal. What is happening to the branch's motion at the time?
The acceleration is constant.
The velocity is constant.
The acceleration is increasing.
The velocity is increasing.
Samu Castillejo is about to put an object that has a mass of 127 kg on a table that can support up to a force of 1000 N of force, will the table be able to support the object?
The table will be able to support the mass.
The table will not support the object.
The table will not be able to support the object after an increased period of time.
How much tension would Karim Adeyemi need to pull an object at a rate 10 m/s^2 if the mass of the object is 27 kg. What force does he need to pull up the bucket at this speed?
500 N of force.
27 N of force.
18 N of force.
270 N of force.
Luiz Araujo is playing soccer and the soccer ball has a mass of 0.45 KG. If Luiz Araujo passes the ball to his teammate with a force of 20 N, what will the acceleration of the ball be?
9 m/s^2
32 m/s^2
20 m/s^2
44 m/s^2
A box is being pushed up an inclined plane. What are the forces acting upon it?
Force Applied, Normal Force, and Force of Gravity.
Force Applied, Normal Force, Force of Gravity, and Friction Force.
Force of Tension, Normal Force, Force of Gravity, and Friction Force.
Force of Tension, Normal Force, and Force of Gravity.
Ansu Fati pushes a 2 KG box and a 1 KG box. He pushes the 1 KG box with a force of 10 N and for the 2 KG box, he applies double that force. However, he realizes even though he applied double the force, the 2 KG box doesn’t move faster. Why doesn’t it move faster?
It doesn’t move faster because even though the 2 KG box has double the inertia, the doubled force on it causes the same accel. because the force to mass ratio is the same for both objects.
It doesn’t move faster because the force of gravity for the 2 KG box is stronger, causing it to slow down more, even with a greater force applied
It doesn’t move faster because every object will have the same acceleration with a different inertia and different force applied.
Alexia Putellas is trying to move an object that is 10 kg in mass but is unable to make it budge. What type of friction is the she facing?
Complete kinetic friction.
Partial kinetic friction. and partial static friction.
Complete static friction.
No frictional force is present.
A rock that weighs 2kg is thrown at a car that weighs 1200kg. Which relationship expresses the forces in the system?
Both objects exert equal forces.
The car exerts a force on the rock, but the rock does not.
The rock exerts a force on the rock, but the car does not.
