Front

When a heavy football player and a light one run into each other, who exerts more force?

Back

They are equal

Front

If a ball of cheese is fired into frictionless space, the amount of force needed to keep it going equals?

Back

zero, since no force is required to keep it moving.

Front

A(n) __________ is a push or pull.

Back

force

Front

Why are we able to accelerate forward when starting to run?

Back

The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.

Front

When a large truck pushes a small car with a given force, the small car is applying an equal and opposite force on the truck.

Back

True

Front

What is Newton's First Law?

Back

An object at rest stays at rest, an object in motion stays in motion.

According to Newton’s Law of Inertia, which object will change its motion? Options: A bike rider on a smooth and level road, pedaling at a constant rate., A train pulling on another train, each with the same amount of force., A chair sitting on the floor with balanced forces acting in opposite directions., A ball rolling across the floor with friction acting in the opposite direction.

Back

A ball rolling across the floor with friction acting in the opposite direction.

When a bowling ball strikes a bowling pin, the force applied by the pin to the ball -

Back

is equal to the force applied by the ball.

According to Newton's Second Law, how do you calculate force?

Back

Multiply mass and acceleration
