OPTIONAL: ICP-physics final exam review

The combination of all the forces acting on an object is called the

• total force
• union of forces
• super force
• net force

If the net force acting on a stationary object is zero, then the object will

• accelerate in the direction of the strongest force
• remain at rest
• begin moving backwards
• decelerate at a steady rate of speed

If the net force on an object is zero then the object has

• reaction forces
• action forces
• balanced forces
• unbalanced forces

A tug-of-war that results in one team pulling the other across the line is an example of

• reaction forces
• action forces
• balanced forces
• unbalanced forces

An object is in motion when

• you observe the object move
• the object's speed increases
• the object changes position relative to a stationary reference point
• the object changes position relative to a stationary starting point

Which acceleration will result in an increase in speed?

• 0 m/s²

• 4 m/s²

• -15 m/s²

• all of the above

An object that changes position relative to a reference point is

• stationary (not moving)
• in motion
• moving at a constant speed
• moving at a constant velocity

The _______________________ of an object consists of its speed and direction.

• velocity
• instantaneous speed
• average speed
• displacement

When the motion of an object is shown by straight line on a distance vs. time graph with the distance on the y-axis, the slope of the line is the:

• distance travelled
• displacement
• speed
• time of travel

Displacement must always indicate

• velocity
• direction
• speed
• time of travel
