Calculating Mass and Acceleration in Physics Scenarios

The video tutorial explains how to calculate mass, acceleration, and net force using Newton's second law. It covers examples involving a car, a ball, a papaya, and a crate, demonstrating the application of the formula F = ma. The tutorial emphasizes unit conversion and the importance of consistent units in calculations.

What is the formula used to calculate mass when force and acceleration are known?

• m = F/a

• F = ma

• a = F/m

• F = m/a

If a car accelerates from rest to 40 m/s in 10 seconds with a force of 200 N, what is its mass?

• 100 kg

• 80 kg

• 50 kg

• 20 kg

How do you calculate acceleration when a force is applied to a ball?

• a = F - m

• a = F + m

• a = F/m

• a = m/F

What is the acceleration of a 0.40 kg ball hit with a force of 16 N?

• 40 m/s²

• 16 m/s²

• 4 m/s²

• 0.4 m/s²

What is the net force on a 3.5 kg papaya with an acceleration of 2.2 m/s²?

• 7.7 N

• 5.5 N

• 10 N

• 3.5 N

Which formula is used to calculate net force when mass and acceleration are known?

• F = m/a

• F = m + a

• F = ma

• F = a/m

How do you find the mass of a crate if the net force and acceleration are given?

• m = F + a

• m = F - a

• m = F/a

• m = a/F

What is the mass of a crate if a net force of 300 N accelerates it at 0.75 m/s²?

• 200 kg

• 300 kg

• 400 kg

• 500 kg

What unit is equivalent to 1 Newton?

• 1 m/s²

• 1 kg/s²

• 1 kg m/s

• 1 kg m/s²

What happens to the units when calculating mass using the formula m = F/a?

• Units cancel out to leave m/s²

• Units cancel out to leave m/s

• Units cancel out to leave N

• Units cancel out to leave kg
