Physical Science: Unit 4 - Intro to Forces

What type of force pulls down on an object?

• Normal

• Friction

• Gravity

• Applied

This type of force is what is prevents you from falling through the floor when walking in the hallway.

• Normal

• Gravity

• Frictional

• Applied

A car is moving at a constant velocity to the east. What direction is the acceleration acting in this scenario?

• East

• West

• North

• South

• There is no acceleration

An object is speeding up towards the right. What direction is the acceleration acting upon it?

• Left

• Right

• Up

• Down

An object slows down as it slides across a table due to friction. What direction is the net force?

• Same direction as the object is moving

• Opposite direction as the object is moving

• There is no net force

If an object that is moving at a constant velocity experiences no net force, it will

• Speed up

• Slow down

• stay at rest

• continue moving at the same velocity

If an object at rest experiences a net force to the left, it will

• accelerate towards the left

• accelerate towards the right

• stay at rest

If an object experiences a net force in the opposite direction that it is moving, it will

• Speed up

• Slow down

• Stay at rest

• Continue on with a constant velocity

If you were to travel to Venus, which of the following would change?

• Your weight

• Your mass

• Both your weight and your mass

• Nothing would change

Which of the following is considered a non-contact force that we have been talking about?

• Friction

• Tension

• Normal

• Gravity
