What mass would a 50 N force accelerate at 25 m/s/s?

Front

2 kg

Back

Newton's First Law of Motion

Front

"An object at rest tends to stay at rest; an object in motion tends to stay in motion."

Back

As the mass of a planet increases, its gravitational force:

Front

increases and it would have a greater gravity

Back

Which object would accelerate the fastest if the same force was applied: 1 kg, 4 kg, 6 kg, 10 kg

Front

1 kg: As mass decreases, acceleration increases

Back

As mass increases, acceleration

Front

decreases

Back

acceleration

Front

a change in velocity/speed

Back

As force increases, acceleration:

Front

increases

Back

acceleration/force relationship

Front

the more force you apply, the greater the acceleration

Back

inertia

Front

the tendency of an object to resist a change in its motion

Back

speed

Front

how fast the position of an object changes with time at any moment; calculated s=d/t

Back

Which force would produce the greatest acceleration on a 5 kg mass: 1 N, 4 N, 6 N, 10 N

Front

10 N: As force increases, acceleration increases

Back

gravity

Front

A force of attraction between objects that is due to their masses.

Back

force

Front

a push or pull that acts on an object

Back

velocity

Front

speed AND direction

Back

acceleration/mass relationship

Front

the greater the mass, the more force necessary to get an object to accelerate

Back

friction

Front

a force opposes the motion of another object; making the object slow down, or giving it traction to get moving

Back

F=

Front

ma

Back

mass

Front

the measure of the amount of matter in an object

Back

A 35 N force would acceleration a 7 kg mass at:

Front

5 m/s/s
