IG Physics Section 2

When a student traveled to the moon 

• their mass stayed the same
• their weight stayed the same
• their weight increased
• both their mass and weight remained constant

Instrument used to measure mass

• balance
• spring
• rule
• weights

Instrument used to measure weight

• balance
• Newton meter
• pendulum
• rule

Weight is

• a gravitational force
• a gravitational field
• a mass
• a gravitational acceleration

The product of mass and acceleration is

• net force
• friction 
• weight
• velocity

Air resistance is a form of 

• thrust
• friction
• weight
• acceleration

If there is no resultant force acting on an object it will 

• remain at rest 
• continue at a steady velocity
• remain at rest or continue at a steady velocity
• slow down

When an unbalanced force acts straight on to an object in motion for a certain period of time

• it will cause a change of momentum
• it will stop the object
• it will slow the object
•  it will make the object move in a circle

When an unbalanced force acts perpendicular to the direction of motion of a body it will cause

• the object to move in a circle
• the object to slow down
• the object to speed up
• the object to maintain a constant velocity

The formula for momentum

• p=mv
• m=pv
• p=m/v
• p=v/m
