What does this graph represent?
Constant Speed
Acceleration
Deacceleration
Not moving
Total distance divided by total time, for an object shows:
acceleration
the size of one's toupee
absolute speed
average speed
Which best explains why we are able to accelerate forward when starting to run?
As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.
No acceleration takes place. Runners are always at a fixed velocity.
The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.
The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward
When a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck.
True
False
An archer shoots an arrow. The action force is the bowstring against the arrow, the reaction force is...
Air resistance against the bow
the arrow's push against the bowstring
the grip of the archer's hand on the bow
A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force (without any additional forces action on it) against the bat of...
Less than 1, 000 N
1,000 N
More than 1,000 N
What is the reaction force to a foot pushing down on the floor?
The foot going through the floor
The floor pushing back against the foot
The floor breaking to the foot
According to Newton's Third law the strength or magnitude of forces will be...
smaller
equal
larger

What happens when two objects, such as a baseball and a bat, collide?
They hit each other with the same force in the same direction.
They hit each other with the same force in opposite directions.
They hit each other with unequal force in opposite directions.
One remains still while the other one moves in the same direction.
Newton's Second Law of Motion states...
An object at rest will remain at rest and an object in motion will remain in motion
the law of inertia
An object acted on by an unbalanced force will accelerate in the direction of the force.
What is the formula for solving force?
mass x acceleration
force / mass
mass x velocity
distance / time

more
less
same

less
more
same amount
Which of the following best describes Newton's First Law of Motion?
An object will remain at rest or in uniform motion unless acted upon by an external force.
For every action, there is an equal and opposite reaction.
Force is equal to mass times acceleration.
The gravitational force between two objects is proportional to their masses.
A car is moving at a constant speed on a straight road. According to Newton's Laws, what can be said about the forces acting on the car?
The forces are balanced.
The forces are unbalanced.
There is no force acting on the car.
The car is accelerating.
