A student claims that unbalanced forces acting on an object in motion can cause all of the following results:

* The object could stop moving

* The object could speed up

* The object could change directions

The best evaluation of this student’s claims is that -

Which two measurements are needed in order to calculate the speed of an object in motion?

The simplified graph shows the motion of an object as measured and recorded in consistent units of time and distance. From the graph, it can be concluded that the object was moving -

Time and distance data for a bicycle is provided in the graph.

According to the data in the graph, what was the average speed of the bicycle?

It takes five hours to drive from Fort Worth to Midland, which is a distance of 300 miles.  What would be the average speed for this trip? 

States that if the net force acting on an object is zero,the motion of the object does not change

The starting point you choose to describe the location or position of an object

States that if the net force acting on an object is zero,the motion of the object does not change

The frictional force between air and objects moving through it

Desribes an object's distance and direction from a reference point

A contact force that one resists the sliding motion of two surfaces that are touching

The process of changing position

A force that one object applies to another object without touching

The difference between the initial, or starting point and it's final position

The distance an object moves in a unit of time

A push or pull one object applies to another object that is touching it

The speed and direction of a moving object

Shows how distance and time are related

A measure of how quickly the velocity of an object changes

States that acceleration of an object is equal to the net force exerted on the object divided by the object’s mass

States that for every action, there is an equal and opposite reaction

The ability to cause change

Energy due to motion

Stored energy due to the interactions between objects or particles

The transfer of energy that occurs when a force is applied over a distance...

Energy carried by electromagnetic waves

The energy that an electric current carries is a form of kinetic energy

Energy carried by sound waves

a force that is applied to an object by a person or another object.

two forces acting in opposite directions on an object, and equal in size

an event or process that leads to a result or change

the moment when two objects hit each other

the straight path an object can move along

the ability to do work; the ability to move or cause change in matter

the same in quantity, size, degree, or value

a push or a pull that causes an object to stop, move or change direction

a force between an object and the surface it is moving over; the force that causes a moving object to slow down when it touches another object

the force that attracts an object toward the center of the earth, or toward any other physical body having mass

the tendency of an object to do nothing or remain unchanged

to reach a conclusion using evidence and reasoning

the amount of matter that makes up an object

anything that has mass and takes up space

the sum of all forces acting on an object; measured in Newtons

the SI unit of force

an object at rest stays at rest (or an object in motion stays in motion) unless acted on by an unbalanced force; the Law of Inertia

the greater the mass of an object being accelerated, the greater the amount of force needed to accelerate the object; the Law of Force and Acceleration

for every action, there is an equal and opposite reaction; the Law of Action/Reaction

acting or going in the reverse direction

Which inclined plane requires the most force to push the ball to the top?

A student is helping his neighbor move a new dishwasher into their house. The house has three steps on the front porch that cause the porch to be 2 meters above the ground. Which method requires the least amount of force to get the dishwasher from the ground to the porch?

Students want to raise a large crate from the ground to a deck several feet above the ground. They know it will be easier to move the crate along an inclined plane because the inclined plane will —

All of the following are examples of inclined planes except —

Which of the following inclined planes would require the least amount of force to lift a box?

Robert is using an inclined plane to move a heavy box into a truck bed that is two meters off the ground. Which of the inclined planes should Robert use to get the greatest mechanical advantage?

Which simple machine increases the distance over which a load travels and reduces the needed force?

A worker needs to load a heavy box onto a truck. The worker uses a ramp to move the box because the ramp...

The diagram shows two ramps that a person could use to raise a 10-kilogram cardboard box to a height of 1 meter. Which statement correctly describes the force required to raise the box using the ramps?
