General Science Unit 3, Part 2 Newton's Laws, Momentum, Impu

Newton's 1st Law states...

• An object at rest will remain at rest and an object in motion will remain in motion unless acted on by an outside force.

• F = ma

• For every action force, there is an equal and opposite reaction force.

According to the relationship (F = ma), what would be the acceleration of a 3 kg object being pushed by a 6 N Force?

• 18 m/s²

• 9 m/s²

• 3 m/s²

• 2 m/s²

A baseball is thrown by an astronaut in deep space. There are no other forces or air resistance. What happens to the ball after leaving the astronaut's hand?

• It speeds up

• It slows down

• Its speed remains constant

• The ball starts to curve downward

The tendency of an object to resist changes in its motion is...

• inertia
• force
• acceleration
• velocity

When all the forces on an object are equal and opposite, & the net force is zero, that's...

• balanced forces
• unbalanced forces
• terminal velocity
• reaction forces
