an equal and opposite force
Give 1 example of an onomatopoeia.
Buzz, boom, click, whoosh, shoom, etc.
Why would a ball thrown in space continue to move??? (Use 1 of Newton's Laws In Your Answer.)
Because there is no outside force acting on it and Newton's 1st law says an object in motion stays in motion unless acted on by an outside force.
What are the units for mass? acceleration? force?
Kilograms (kg), m/s2, Newtons
A car is moving forward. Give 1 force that is opposing the car?
Opposing forces would be the air resistance and friction between the car's tires and the ground
What is sodium's chemical symbol?
Na
The name of the property of matter that says it wants to resist change in motion is called...
Inertia
John Doe is wanting to do an experiment over Newton's 2nd law. He rolls 2 toy cars down a ramp and applies 5 N of force to each car:
Toy Car #1 has a mass of 4.5 kg
Toy Car #2 has a mass of 2 kg
Which toy car will have a greater acceleration?
Toy car #2
A test crash car hits a wall with 750 Newtons of force. How many Newton's of force does the wall apply to the car?
750 Newtons
What is full of holes but still has water?
A sponge.
Finish the sentences: The first law states that an object at rest will ______________ and an object in motion will __________________ unless a ______________ acts on it.
stay at rest / stay in motion / force
John Doe is wanting to do an experiment over Newton's 2nd law. He rolls 2 toy cars down a ramp and applies 5 N of force to each car:
Toy Car #1 has a mass of 2.5 kg
Toy Car #2 has a mass of 10 kg
What are the accelerations for each of the cars?
Car #1: 2 m/s2
Car #2: 0.5 m/s2
What is the difference between speed and velocity?
Velocity has direction

If you roll a ball along the ground what force is pushing down on the ball? What force is going in the opposite direction that the ball is rolling?
Gravity / Friction
A truck has a mass of 10,330,467 grams and accelerates at 4 m/s2. What is the force?
41,320 N
2 tug of war teams consisting of 3 people each are trying to get a dub. Each person on team #1 (on the left side of the rope) is pulling with 50 N of force. Each person on team #2 (on the right side of the rope) is pulling with 20 N of force.
Draw a picture (or force diagram) and calculate the net force (give the number of Newtons AND direction.)
90 N left
How many seconds are in a year?
