ICP Unit 2 Test

Speed with a direction is:

• Distance

• Displacement

• Velocity

• Acceleration

Newton's first law states.

• An object at rest will remain at rest unless acted upon by an outside force. An object moving in a straight line at a constant speed will continue moving as such unless acted upon by an outside force.

• The net force action on the object is equal to its mass times its acceleration.

• For every action there is an equal and opposite reaction.

• The attraction between two objects is proportional mass of the two objects multiplied together divided by the distance between them squared.

What is the difference between distance and displacement?

• There is no difference

• Displacement is distance with direction.

• Displacement is speed with direction.

• Displacement is used in space, distance is using

10 m/s/s down would be a measurement of:

• acceleration

• position

• velocity

• time

How is velocity calculated?

• Velocity equals Acceleration

• Velocity equals Speed divided by time.

• Velocity equals the change in displacement divided by time.

• Velocity equals displacement times time.

What is the description of acceleration?

• Acceleration is the rate of change of position of an object.

• Acceleration is the rate of change of force of an object.

• Acceleration is the rate of change of direction of an object.

• Acceleration is the rate of change of velocity of an object.

Which force results from the mass of two objects?

• Gravity

• The Electromagnetic Force

• The Strong Nuclear Force

• The Weak Nuclear Force

What does the electromagnetic force depend on?

• The interaction of charged particles.

• The mass of the two particles

• The quark colors of subatomic particles

• The gas pressure in a closed space.

What is the best description of force.

• A push or a pull

• speeding up

• moving an object

• Slowing down

What will a spaceship coasting in deep space in a straight line do?

• Slow down as it moves through space.

• Move at the same speed unless a net force is applied.

• Speed up on its own with no force applied.

• Just move in a curve even though no other bodies are near.
