action force
reaction force
net force
inertia
The head of a hammer is often made of steel. This makes the head heavy, which helps create a strong force for driving nails. Steel is also strong. The head of a hammer must be strong to resist what force?
The force of the air resistance on the moving hammer
The force of the person using the hammer
The force of gravity pulling down on the hammer
The force of the nail pushing in the opposite direction
Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass on top of the block and pulled it 50 cm across the table. Which of the following changes to their set-up would result in a larger force reading on the spring scale?
Sliding the block 60 cm
Attaching a larger spring scale
Using a 20g mass
Using a circular piece of wood
Using what you know about F=ma, which ball would have the greater force if traveling at the same acceleration? Tennis ball=1 ounce and the baseball=5 ounces
An object's inertia depends on its mass.
true
false
