100
The total change in position of an object, regardless of direction.
What is distance?
100
A push or a pull on an object
What is a force?
100
A horse runs 30 meters in 15 seconds. What is its speed? (Include Units!)
2 m/s
100
Mr Minotti pulls on an object with a force of 100 N. His friend pushes on the object in the same direction with a force of 120 N. What is the net force on the object?
220 N.
100
An object accelerating towards the ground, with no other forces acting upon it.
What is free fall?
200
The distance and direction of an objects change in direction.
What is displacement?
200
The force the opposes the sliding motion of two surfaces that are touching each other.
What is friction?
200
A satellite's speed is 5000 m/s. After one minute, it is 10,000 m/s. What is it's acceleration? (Include Units)
5000 m/s/min
200
In a game of tug of war, Team 1 pulls on the rope with a force of 10,000 N. Team 2 pulls with a force of 8,000 N. What is the net force on the rope?
2000 N towards Team 1.
200
A property of matter where it wants to stay at rest or move at a constant velocity unless acted upon by an external force.
What is inertia?
300
The rate of change of an object's distance per unit of time, with direction.
What is velocity?
300
"An object tends to move at a constant velocity unless acted upon by an unbalanced force."
What is Newton's First Law of Motion?
300
A boy weighing 50 kg runs at a velocity of 8 m/s west. What is his momentum? (Include Units)
40 kg m/s
300
What is the weight of an object with mass 10 kg on earth?
98 N
300
Mr Minotti is walking at a constant velocity of 3 m/s north on Beneva Rd. What is the net force acting upon him?
0 N
400
The rate of change of an object's velocity.
What is acceleration?
400
An object's acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass.
What is Newton's Second Law of Motion?
400
A car has an acceleration of 10 m/s^2. If it accelerates from rest for 3 seconds, what is its final velocity? Include units
30 m/s
400
A dog pulls a 45 kg sled with an acceleration of 5 m/s^2. What is the net force on the sled?
225 N
400
Bobby runs 3 miles to 7-11 and then runs three miles back home. What is his displacement?
0 miles.
500
The property of a moving object that equals its mass times velocity.
What is momentum?
500
Forces occur in pairs with equal magnitude and opposite direction.
What is Newton's Third Law?
500
How long would it take a car to travel a distance of 300 miles at a speed of 60 miles/hour. (Include units)
5 hours
500
What is the mass of an object being pushed with a net force of 500 N with an acceleration of 25 m/s^2? (Include Units!)
20 kg
500
