Newton's 2nd Law

Jeremiah is pulling 2 ropes at the same force of 80 N each. Rope #1 is 10 kg and Rope #2 is 12 kg. Identify the mass of Rope #1.

• 80 N

• 12 kg

• 10 kg

• 22 kg

Jeremiah is pulling 2 ropes at the same force of 80 N each. Rope #1 is 10 kg and Rope #2 is 12 kg. Identify the force on Rope #2.

• 10 kg

• 80 N

• 12 kg

• 40 N

Car A and Car B are both 2000 kg. Oscar pulls Car A with 500 N of force and pulls Car B with 250 N of force. What is the force used on Car B?

• 250 N

• 500 N

• 2000 kg

• 1000 kg

Acceleration depends on:

• mass and pull

• push and pull

• weight and force

• mass and force

As _________INCREASES, and __________ DECREASES, acceleration INCREASES.

• mass, force

• weight, force

• force, mass

• force, weight

Which object will accelerate faster?

A- 1000 N, 25 kg

B- 1000 N, 50 kg

C - 1000 N, 10 kg

• A

• B

• C

• They accelerate the same

Which object will accelerate faster?

A- 450 N, 5 kg

B - 25 N, 5 kg

C - 400 N, 5 kg

• A

• B

• C

• They accelerate the same

Object 1 - 1500 N, 10 kg

Object 2 - 1500 N, 15 kg

If we know F = m*a, which object accelerates faster and what is their rate of acceleration (m/s^2)?

• Object 1; 150 m/s^2

• Object 2; 22,500 m/s^2

• Object 1; 15,000 m/s^2

• Object 2; 100 m/s^2
