Unit 1-4 REVIEW

Front

What happens to the ball's speed if the force applied by the club is doubled?

Back

The speed of the ball doubles.

Front

What is the formula to calculate force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What is the acceleration of a 10 kg object when a force of 50 N is applied?

Back

Acceleration = 5 m/s².

Front

What is cohesion in terms of water molecules?

Back

Cohesion is the property of water molecules that allows them to stick to each other.

Front

What is adhesion in terms of water molecules?

Back

Adhesion is the property of water molecules that allows them to stick to other substances.

Front

What is capillary action?

Back

Capillary action is the ability of water to move through narrow spaces, such as plant roots, due to cohesion and adhesion.

Front

What is the mass of the bike in the given scenario?

Back

The mass of the bike is 98 kg.

Front

How do you calculate acceleration?

Back

Acceleration = Net Force / Mass.

Front

What is the net force acting on Rider 1 if they apply a forward force of 2100 N?

Back

Net force = 2100 N - (mass of bike + rider) × gravity.

Front

What is the significance of surface tension in water?

Back

Surface tension allows water to form droplets and enables small objects to float on its surface.
