Amplify Force and Motion, Chapters 3 and 4

Front

What happens to the velocity of objects in a collision if they have different masses?

Back

Their changes in velocity will be different.

Front

What is the best model to depict the force applied in a collision?

Back

A force diagram showing the direction and magnitude of forces involved.

Front

How does mass affect the rate at which two objects with the same initial velocity stop or slow down?

Back

Objects with different masses will stop or slow down at different rates due to the same friction force.

Front

What can different surfaces have in terms of friction forces?

Back

Different surfaces can have different strengths of friction forces.

Front

What is necessary to link evidence to a claim in a scientific argument?

Back

Reasoning is necessary to connect evidence to a claim.

Front

Define 'force' in the context of motion.

Back

A push or pull that can change the motion of an object.

Front

What is 'friction'?

Back

A force that opposes the motion of an object when it is in contact with another surface.

Front

Explain the concept of 'inertia'.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

The acceleration of an object is inversely proportional to its mass when the same force is applied.

Front

What is 'momentum'?

Back

Momentum is the product of an object's mass and its velocity.
