A rocket is traveling through the atmosphere at a constant velocity. Which of the following is true?
The rocket's engine is producing an unbalanced force that keeps the rocket in the air.
All of the forces acting on the rocket are balanced.
The rocket exerts a greater force on its exhaust gases than the exhaust gases exert on the rocket.
The rocket is moving, so some net force must be acting on it.
The units for Force are:
Newtons
Joules
m/s
kg
Student A and B are standing on a skateboard. Student A pushes gently on Student B to start her moving. Student B starts moving away from Student A. What will happen to Student A and why?
Student A will not move, because no forces are acting on her.
Student A will move toward Student B, because the same force is acting on both of them.
Student A will immediately stop moving because of friction.
Student A will move away from Student B, because an equal and opposite force pushes on her.
How is an object’s mass related to the force needed to accelerate the object?
Mass determines the direction of the force needed.
Mass determines the type of force needed.
The greater the mass, the greater the force needed.
The smaller the mass, the greater the force needed.
The full shopping cart has a mass of 75 kg and an empty one has a mass of 20kg. How much force would you need to accelerate the empty cart?
We would need the same amount of force.
We would need less force.
We would need more force.
We would not need force at all.
Which statement is a valid description and explanation of the guy’s motion based on evidence from the diagram.
The fridge’s force is balanced due to the overall forces of gravity and friction being less than then the force of the push.
The fridge’s force is unbalanced due to amount of push not equaling the amount of gravity.
The fridge’s force is balanced due to the amount force exerted by the freezer and friction thus equaling to the force of push.
The fridge’s force is unbalanced due to the larger amount push force being exerted compared to the smaller amount of frictional force.
George rolled a ball down a hill. The ball stopped before it reached the bottom of the hill. Which of these is most likely the reason the ball stopped rolling?
Mass
Inertia
Friction
gravity
A student connected a wooden block to a spring scale. He slowly pulled on the spring scale until the block began to move. The picture shows the experiment and the point on the spring scale when the block began to move.
Which statement best describes the forces acting on the wooden block? Think in terms of pull and friction.
The force on the wooden block was less than 0.4 N.
The force on the wooden block was more than 0.4 N.
There were no forces on the wooden block before it was moving.
The forces on the wooden block were unbalanced before it was moving.
Describe the motion of an object that has balanced forces acting on it.
An object will accelerate.
An object will not move or maintain a constant speed.
An object will slow down.
An object will change directions
In this picture, Stan is attempting to move the refrigerator to the kitchen. Will he be successful?
No, the forces acting against him are too much.
No, gravity and friction will stop him.
Yes, the net force is 35 N to the left.
Yes, the net force is 25 N to the right.
Why does a semi-truck stop a longer distance from a red light than a regular sized car?
Truck drivers are not in a hurry.
A regular size car takes a long time to come to a complete stop.
The semi-truck has more mass and it takes a larger force for it to stop.
The regular size car has less mass but it takes a larger force for it to stop.
