A 10 kg box is pushed with a net force of 20 N. According to Newton’s second law, what
is the acceleration of the box? Use the formula a= F/m
The acceleration is 0.5 m/s².
The acceleration is 2 m/s².
The acceleration is 10 m/s².
The box will not accelerate since the forces cancel out.

Based on the data table below, what conclusions can you draw about how mass and force affect acceleration? (Select THREE correct answers.)
When the mass increases, acceleration decreases if the net force stays constant.
When the net force increases, acceleration decreases if the mass stays constant.
Acceleration remains the same if both mass and force increase proportionally.
If net force decreases and mass is constant, the acceleration decreases.
When the net force decreases, acceleration increases if the mass stays constant.
