Go To Score Card

Forces: 200
• Question:
• Push or pulls are this in physical science.
• What is a force?

Back

Forces : 400
• Question:
• This is required to change the motion of an object.
• What is an unbalanced force?

Back

Forces : 600
• Question:
• The unit used to measure force is this.
• What is Newton?

Back

Forces : 800
• Question:
• Balanced forces affect the motion of an object in this way.
• What is no acceleration occurs (no change in motion)?

Back

Forces : 1000
• Question:
• The forces that act on a block resting on a tabletop.
• What are normal force (Fn) and gravitational force (Fg)?

Back

Gravity: 200
• Question:
• This force pulls objects towards the Earth.
• What is gravity?

Back

Gravity : 400
• Question:
• Acceleration due to gravity has this rate.
• What is 9.8 m/s2?

Back

Gravity : 600
• Question:
• When gravity is the only force acting on an object it is doing this.
• What is free falling.

Back

Gravity : 800
• Question:
• This law states that all objects have a gravitational force and exert them on other objects.
• What is The Law of Universal Gravitation?

Back

Gravity : 1000
• Question:
• Gravitational force between two objects is affected by these two factors.
• What are mass and distance.

Back

Net Forces: 200
• Question:
• When two forces are equal and oppose each other while pulling on an object, this is the net force.
• What is zero?

Back

Net Forces : 400
• Question:
• If a chair is pushed west with a force of 2000N and friction opposes it with a force of 150N, this is the net force.
• What is 1850 N west?

Back

Net Forces : 600
• Question:
• When calculating net force, this should be done with all forces acting in the same direction.
• What is add them together

Back

Net Forces : 800
• Question:

Miscellaneous: 400
• Question:
• If there is no air resistance and a marble and a steel ball are dropped from the same height, they will do this.
• What is hit the ground at the same time?

Back

Miscellaneous: 600
• Question:
• If an object is in free fall (with no air resistance) for 4 seconds, this will be it’s velocity at the end of the 4 seconds.
• What is v=g*t
• = 9.8 m/s2 * 4 s
• =39.2 m/s

Back

Miscellaneous: 800

• What is gravity?

Back

Miscellaneous: 1000
• Question:
• When a skydiver’s parachute first opens, this force becomes the largest force acting on them.
• What is air friction?
