GCSE Physics Unit 2 2.2/6.2 Newton's Laws Quiz

According to Newton's first law, when will an object remain at rest or at a constant velocity?

• When acted upon by an external resultant force

• When in motion

• When in water

• When in space

What is the formula to calculate weight?

• Weight = mass × force

• Weight = mass × velocity

• Weight = mass × gravitational field strength

• Weight = mass × acceleration

What does Newton's second law help calculate?

• Stopping distance

• Speed

• Force

• Velocity

According to Newton's third law, if a body A exerts a force on body B, then body B exerts an equal and opposite force on body A. True or False?

• True

• False

• Maybe

• Not sure

What are the forces acting on a skydiver as they fall?

• Friction and weight

• Air resistance upwards and weight downwards

• Gravity and air resistance

• Magnetic force and weight

What happens when the forces on a skydiver are balanced?

• The skydiver slows down

• The skydiver reaches terminal speed

• The skydiver accelerates

• The skydiver stops moving

What causes a skydiver to slow down when they open their parachute?

• Increased air resistance

• Decreased weight

• Decreased air resistance

• Increased weight

How can terminal speeds be achieved with vehicles travelling horizontally?

• By reducing weight

• By increasing engine force forward

• by balancing the driving force and resistive forces

• By decreasing air resistance

What is the difference between weight and mass?

• Weight and mass are not related

• Weight and mass are the same

• Weight is the force of gravity acting on an object, mass is the amount of matter in an object

• Weight is the amount of matter in an object, mass is the force of gravity acting on an object

What is the gravitational field strength on Earth?

• 15N/kg

• 10N/kg

• 5N/kg

• 20N/kg
