When you tell the direction and speed of an object, you give its

__________ is the change in speed or direction of an object's motion.

A train is traveling at a speed of 75 mph. Suddenly, it starts going faster. What caused the increase in speed?

What do you need to measure to find the speed of a moving car?

Which describes velocity?

Which example shows NO acceleration?

If these boys are pulling with the same amount of force, is it a balanced or an unbalanced force?

The more mass an object has, the more ___________ it has.

A picture is hanging on a wall and does not move. This is an example of -

A person not wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops.
This is an example of -

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is -

For every action there is an equal and opposite reaction. This is -

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). This is -

Any push or pull from one object to another is called (a) -

Two toy race cars are going to be raced down the same ramp. Which information is most helpful in predicting which car will win the race?

The swimmer moves her hand down and to the left and her body goes forward to the right. This is an example of -

A rocket is sent into space.  When the power dies out, the rocket will just keep floating and moving in space forever (unless an unbalanced force, such as a meteor, runs into it).
This is an example of -

A soccer ball accelerates more than a bowling ball when thrown with the same force. This is an example of -

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass/inertia. This is an example of -

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction. This is an example of -

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. This is an example of -

If a force of 26 N is exerted on two balls, one with a mass of 5 kg and the other with a mass of 8 kg, which ball will have the greater acceleration?  (F=ma)

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

If you are driving forward and suddenly brake, what would happen to your body and which law does that demonstrate?

In a football game, two players tackle each other so hard that they both fly in opposite directions after they hit each other.  This is an example of -

A student leaves a pencil on a desk and it stays there until I pick it up.  This is an example of -

A person in car slides to the right when going through a very sharp left turn on the highway. This is an example of -

If you exert a net force of 20 N on a 2-kg object, what will its acceleration be?

A force of 20 N acts upon a 5 kg block. What is its acceleration? 

The SI units for force are...

A soccer player kicks a ball with their foot and their toes are left stinging. This is an example of -

Two students are in a baseball game. One student hits a ball hard and it has a greater acceleration than the 2nd student who bunts the ball lightly.  This is an example of -
